AAK Cartridge Relief Valve Optimized from HydraForce Std. Part
Cyrano, an experienced buyer of hydraulic cartridge valves from Greece, encountered difficulties with a batch of hydraulic cartridge relief valves. At the beginning of the year, they developed a hydraulic power unit and used a hydraulic cartridge relief valve purchased from a hydraulic cartridge valve manufacturer in Ningbo. During the commissioning of the hydraulic power unit, the operation was not stable. Their engineer found that when the overflow flow rate changes greatly, it is easy to cause a large change in the pressure at the inlet of the hydraulic cartridge relief valve. The original manufacturer reported that this hydraulic direct-acting relief valve is a standard part benchmarking HydraForce, they should have their engineer to control the system's overflow flow fluctuations, which embarrassed Cyrano. Cyrano found AAK on Google and noticed that AAK has had multiple cases of solving difficult and complex problems for customers. He emailed us to ask, "How to improve the stability of HydraForce's standard hydraulic direct-acting relief valve?". This question is too big to answer. After communication, it was learned that he had encountered a problem matching the standard part of the hydraulic cartridge relief valve with his equipment. The direction is clear, but whether to choose to optimize A to match B or optimize B to match A, there are only these 2 options. AAK engineer asked if it is possible to replace the hydraulic direct acting relief valve with a pilot operated relief valve? AAK can design according to the working conditions. He paid the development fee the next day, and 40 days later, AAK sent samples of the hydraulic cartridge relief valve. Last week, Cyrano informed that after AAK hydraulic cartridge relief valve was installed in the system, when the overflow flow changed significantly, the pressure at the inlet of the hydraulic relief valve did not change much. Their engineers were very happy and there would be no need to change the system. AAK hydraulic pilot operated relief valve can replace HydraForce hydraulic direct acting relief valve, which is actually very simple. The pilot valve and the main valve are combined to form a whole. The pilot valve controls and regulates the overflow pressure, and the main valve functions as an overflow valve. The two ends of the main valve plug are subjected to oil pressure. The main valve pressure spring is made of small stiffness material. When the overflow flow rate changes greatly, the compression amount of the pressure spring does not increase, and the pressure at the oil inlet is stable. 1. AAK hydraulic pilot operated relief valve is equipped with a first liquid chamber and a cavity for installing the valve spool. The first liquid chamber and the cavity are connected through a through hole. One end of the valve spool is located in the through hole, and the other end is connected to a pressure regulating device, which is fixed on the valve body. 2. The main valve seat is provided with an oil inlet and a return port, which are connected to the oil return port. The plug plugs the oil inlet and return ports through their ends and sides, respectively. The plug connects to the valve body through a pressure spring, and the plug has a damping hole. 3. The pressure regulating device consists of a pressure regulating screw and a spring. One end of the pressure regulating screw is connected to the spring, and the other end of the pressure regulating screw is connected to the valve body. The end face of the plug plugged into the oil inlet is a conical surface. AAK hydraulic cartridge pilot operated relief valve, high stability, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak539 Contact:

AAK Hydraulic Cartridge Valve Spool Upgraded Automatic Processing
Last week, the video I sent to Frank about how hydraulic cartridge valve manufacturer AAK processes the valve spool of hydraulic cartridge flow control valves using a centerless grinder was not approved by him, which made me very disappointed and also helped me understand the requirements of German customers for automated production. Frank from Germany needs to develop a hydraulic flow control valve, but there is a requirement for the accuracy of the valve spool, which requires centerless grinding equipment for precision machining. Frank learned that hydraulic cartridge valve manufacturer AAK has this equipment, so he asked me to take a video of the work for his reference. The next day, Frank said, "Why does it still need a person to assist in completing it?"? I realized that Frank rejected the hydraulic cartridge valve manufacturer AAK because of this. But I'm not too worried, because the automated production process is a strong point of hydraulic cartridge valve manufacturer AAK. Although there is no chance for the hydraulic flow control valve this time, Frank, a customer who is meticulous, will definitely return to AAK. 3 days later, I said to Frank, ‘thank you for your reminder. The mechanical arm plan for automatic material retrieval and feeding equipped for the centerless grinder is already in place. It is expected that in 3 months, I will provide a video of the fully automatic centerless grinder processing the hydraulic flow control valve spool. At the same time, I will also send you some previously unmanned fully automatic processing processes’. Let's go back to last week's video to Frank that using a centerless grinder to process the spool of a hydraulic flow control valve. This CNC centerless grinder is equipped with an automatic conveyor belt. The operator only needs to place the rough machined valve spool on the conveyor belt, and the valve spool is sequentially fed into the grinding area. After one machining is completed, it is automatically placed in the next one. The grinding wheel adopts diamond grinding wheel, which provides a basis for the stable accuracy of the valve spool due to its hardness and wear resistance. The control system of the centerless grinder is stable, with no faults during long-term processing, and the stability of grinding provides assurance for the accuracy and stability of the valve spool. Thanks to Frank's advice again. In fact, the more requirements customers have for you, the more they hope you will grow until you meet the qualifications of their preferred supplier. I like this type of customers. AAK hydraulic cartridge flow control valve, German customer's suggestion, AAK landing, you can also give it a try!

Widely-targeted Metabolomics Database in Rice
Widely Targeted Metabolite Detection MWDB Major Upgrade: 20,000 plant metabolites MWDB (Metware Database) can now detect 20000 types of plant metabolites Since 2014, Metware Biotechnology has been pushing the boundaries of metabolite detection. Our featured product Widely-Targeted Microbiome Metabolomics for Plants has been undergoing a major upgrade this year where our identifiable plant endogenous metabolites rose to 20,000, a doubling from our previous plant metabolomics database of 10,000! Average identified metabolites: 1,300 metabolites detected in real samples Applying this database to the detection of different species or tissue types, the average number of substances detected in a sample can be as much as 1300. Below, we present real outputs using Oryza sativa samples. Unvealing the data: The graph below shows different tissues types from O. sativa averages to 1300 identified metabolites. The data reveals that we can detect over 800 secondary metabolites and over 400 primary metabolites. Our observations here is in concordance with published literature where primary metabolites in plants are relatively conserved ranging around 1000 types, whereas secondary metabolites vary greatly between species and can range from 0.2 ~ 1 million. This is a significant improvement in identifying secondary metabolites in plants. Analysis of detected metabolites: wide-coverage Analyzing the metabolites in various tissues, we find that flavonoids and phenolic acids stands out whereas other metabolites show large differences between tissue types. Due to these differences, it is best to cover all types of metabolites in a metabolomics study. Reference: 1. A multi-omic study uncovers a bZIP23-PER1A–mediated detoxification pathway to enhance seed vigor in rice. 2. Rice metabolic regulatory network spanning its entire life cycle. 3.

Untargeted Metabolomics
What Is Untargeted Metabolomics? HomeMetabolomics ServicesGlobal Metabolite ProfilingUntargeted Metabolomics untargeted metabolomics service The LC-MS untargeted metabolomics is used for unbiased detection of metabolites in samples by liquid chromatography-mass spectrometry and to obtain their qualitative and quantitative information. Untargeted metabolomics data analysis, also known as nontargeted metabolomics analysis, entails comparing the metabolomes of control and test groups to pinpoint distinctions in their metabolite profiles that could be pertinent to specific biological conditions. Technology Introduction The main application of lcms metabolomics is for comparing the case group with the control group to find the metabolites and metabolic pathways that show significant differences between groups, which can provide clues and directions for the untargeted metabolomics research in biomarker development, disease pathogenesis, and drug treatment mechanisms. Technical Features of Untargeted Metabolomics Service Large Curated Database Collected ultra-high sensitinity data of over 280,000 metabolites. Each sample can typically identify 1500-3000 metabolites. Comprehensive Identification Strategy A comprehensive identification of metabolites was performed using four qualitative methods: Matching to in-house standard database; Matching to integrated public database; Matching to AI database; Identify using the metDNA algorithm. Rigorous Quality Control A mature quality control system monitoring all aspects of experimentation from sample preparetion to data collection. Why Untargeted Metabolomics Service Is Used? Genes will tell you what may happen, metabolites tell you what is happening or has happened (Bill Lasley) Metabolomics is the qualitative and quantitative assessment of metabolites (small chemical molecules<1.5 kda). The metabolites are the downstream product of protein activity as well as the result of interactions with environmental exposures, and thus they are closely related to the phenotype. Over the last decade, metabolomics is coming to the forefront as a powerful tool for understanding disease mechanisms. and identifying biomarkers, and has great potential for clinical translation.

Transcriptome+Metabolome
HomeMetabolomics ServicesMulti-OmicsTranscriptome+Metabolome tra , nscriptome metabolome services The transcriptome is an important method to obtain gene expression in a biological system, and the metabolome is the basis and direct readout of the system’s phenotype. The metabolites are the final result of gene transcription under internal and external regulation and are the material basis of the observed phenotype. In the era of systems biology research, biological processes and gene regulatory networks are complex and dynamic. It is often insufficient to use a single dataset to study systems biology. Correlating transcriptomic data that has a large number of differentially expressed genes with differential metabolites detected by metabolomics can pinpoint key genes, metabolites, and metabolic pathways that are closely associated with internal changes in the system, and thereby explain biological problems in a more holistic approach. Technology Introduction of Transcriptomics and Metabolomics Services Correlating transcriptomic data that has a large number of differentially expressed genes with differential metabolites detected by metabolomics and multi-omics can pinpoint key genes, metabolites, and metabolic pathways that are closely associated with internal changes in the system, and thereby explain biological problems in a more holistic approach. Case Study: The Cardamine Enshiensis Genome Reveals Whole Genome Duplication And Insight Into Selenium Hyperaccumulation And Tolerance (Huang Et Al., Cell Discovery 2021) To better understand the mechanisms of Se tolerance in Cardamine enshiensis, the authors constructed the 443Mb genome for C. enshiensis and performed RNA- seq and Widely-Targeted Metabolomics on seedlings treated with water (control) or 400uM sodium selenite. Mechanisms of Se tolerance and hyperaccumulation in C. enshiensis In total, 29,671 differentially expressed genes were identified and a total of 558 metabolites were identified in the leaf tissue of C. enshiensis, of which 127 were differential metabolites. The authors found 10 flavone-related metabolites were altered between the two groups, indicating that flavones play a pivotal role in Se tolerance. KEGG analyses showed the significantly enriched pathways were associated with the biosynthesis of secondary metabolites and flavone/flavonoid/flavonol compounds. A Pearson’s correlation coefficient threshold of r > 0.8 was used to identify the metabolites that were significantly correlated with each gene and the results revealed that 175 transcripts were highly correlated (R2 > 0.96) with tricetin O-malonylhexoside and amentoflavone.

Resequencing+Metabolome
Home Metabolomics Services Multi-Omics Resequencing and Metabolomics resequencing metabolome services The types and quantities of metabolites vary greatly in different species and tissues. The mGWAS (metabolome Genome-Wide Association Study) approach uses population materials, based on resequencing genetic information and metabolomics data to carry out genome-wide association analysis between genomic variations and metabolite quantities. Case Study: Genome-wide association analyses provide genetic and biochemical insights into natural variation in rice metabolism (Chen et al., Nature Genetics 2014) Subspecies specific metabolites between two rice subspecies Using 529 rice leaf materials, a total of 840 compounds were detected by Widely-Targeted Metabolomics. Cluster analysis of these metabolites identified C-glycosylated and malonylated flavonoids accumulated more in the O. indica, while the O. japonica contained large amounts of phenolamides and arabidopyl alcohol derivative compounds. These subspecies-specific metabolites reflect the differentiation of O. indica and O. japonica. SNP analysis and metabolite association of the rice population Using NGS on the 529 materials, 6,428,770 SNPs were screened for further analysis. Simple linear regression (LR) and linear mixed models (LMM) were used for mGWAS analysis and a total of 2,947 major SNPs were identified, corresponding to 634 loci in at least one population. 161 significant loci shown on the Manhattan plot correspond to flavonoids, phenolic compounds, amino acids and their derivatives, terpenoids, nucleic acids and their derivatives, and other known metabolites. In addition, there are 195 loci corresponding to unknown metabolites. Case Study mGWAS assists with annotation of unknown metabolites mGWAS facilitates the annotation of metabolites by associating unknown metabolites with functionally relevant genes. For example, SNP sf1207801034 in the NOMT gene encoding naringenin 7-O-methyltransferase correlated with mr1002 levels, suggesting that this metabolite may be sakuranetin. Subsequently, the mr1002 metabolite was proven to be sakuranetin by comparing the retention time and fragmentation pattern with the chemical standard of this compound. In this study, GWAS was able to annotate 166 unknown metabolites. Case Study Biochemical and functional interpretation of GWAS results In addition to providing insight into the genetic basis of metabolic changes, mGWAS also provide insight into the biochemistry and function of underlying pathways. We can examine previously unidentified candidate genes by (i) finding genes or gene clusters associated with the relevant metabolic signatures encoded by these loci; (ii) clustering candidate genes with homologous genes with known functions; (iii) cross-reference genetic map results. We hope to uncover candidate genes or SNPs valuable for plant physiological or human nutrition. For instance, trigonelline, an N-methyl conjugate of nicotinic acid, has long been reported to regulate various processes, especially abiotic stress in plants, but the enzyme that catalyzes niacin to trigonelline was unknown at the time. Trigonelline levels were significantly correlated with SNP sf0235317720 on chromosome 2, which was in linkage disequilibrium with the Os02g57760 gene encoding an O-methyltransferase protein, indicating that Os02g57760 encodes a key methyltransferase that catalyzes trigonelline biosynthesis. When N-terminal His-tagged Os02g57760 was expressed in E. coli BL-21, we were able to detect niacin:N-methyltransferase activity in soluble protein extracts. Consistent with the in vitro activity, overexpression of Os02g57760 in ZH11 (an O. japonica cultivar with low trigonelline content) resulted in a greater accumulation of trigonelline in the transgenic lines compared to control plants, confirming that Os02g57760 catalyzes trigonelline biosynthesis.
