Andreus is from a hydraulic equipment company in Chile. He has been in purchasing smoothly for 2 years. At the beginning of the year, their company received an inquiry for a batch of personalized excavators, and customer needed prototypes. The hydraulic cartridge counterbalance valve in the hydraulic system is the key. Their engineer asked Andreus to purchase the standard parts of SUN hydraulic cartridge counterbalance valves, but the parameters did not match, and SUN was unwilling to customize. They had to work with a hydraulic cartridge valve manufacturer who had cooperated with them for 4 years to make samples. But the test run was not smooth. When the load pressure was applied, the opening of the main valve spool of the hydraulic cartridge counterbalance valve would change, affecting the flow and causing the main engine to shake. The hydraulic cartridge counterbalance valve manufacturer had no solution but to give up. Andreus contacted more than 10 other hydraulic cartridge valve manufacturers, but still no result after 1 week. The engineer was impatient, and Andreus was worried. Andreus browsed AAK website on Google and clicked the article and product introduction about hydraulic cartridge counterbalance valves for many times. He left us a message: How to keep the hydraulic cartridge counterbalance valve free from load interference and stable flow? I replied: There are many reasons for the problem, which should be analyzed in details. According to the video of abnormal equipment sent by him, as well as the production drawings of the hydraulic cartridge counterbalance valve, AAK engineers judged that the structure should be optimized and AAK is 90% confident to solve the problem. Andreus saw the hope and asked for AAK samples. After 50 days, AAK sent 20 hydraulic cartridge counterbalance valve samples. 1 month later, Andreus informed that after the excavator was equipped with AAK hydraulic cartridge counterbalance valve, the equipment was running stably and the prototype had been sent to the customer. AAK hydraulic cartridge counterbalance valve can resist the pressure fluctuation when the load drops, and the flow is stable. We have made 3 structural optimizations. The hydraulic cartridge counterbalance valve is composed of 5 parts: valve body, valve seat, main valve spool, pilot valve spool and pilot mechanism. 1. The valve seat of the hydraulic cartridge counterbalance valve is connected with the valve body to form a connected first channel, and the extended end of the valve seat butts against the pilot mechanism to form a second channel. 2. The main valve spool of the hydraulic cartridge counterbalance valve is provided with a throttling groove, the other end is connected with the inner cavity of the main valve spool, and the pilot drive part is used to drive the pilot valve spool. 3. One end of the pilot valve spool of the hydraulic cartridge counterbalance valve is slidably arranged in the inner chamber of the main valve spool, and the other end is connected with the pilot mechanism. The pilot valve spool is also provided with a throttling groove, an axial pilot valve spool chamber and an orifice. The optimized balance structure of the hydraulic cartridge counterbalance valve, which connects the pilot valve spool and the inner chamber of the main valve spool, enables the oil pressure through the 2 channel ports to form a balance on the pilot valve spool, and the opening of the main valve spool under the force of the pilot mechanism can not be affected by the load pressure fluctuation. AAK hydraulic cartridge counterbalance valve, no load interference, you can also try a small order! https://www.aakindustry.com/info-det , ail/counterbalance-valves-aak456

Chapin is from Canada and has purchased hydraulic cartridge valves in Ningbo for 5 years. At the beginning of this year, their hydraulic cylinder needed hydraulic directional control cartridge valve. He found a hydraulic directional control cartridge valve manufacturer in Ningbo to test the sample, but it was not successful. When the external load of the oil cylinder suddenly changes, the response of the hydraulic direction control cartridge valve is slow, and the shunt accuracy cannot keep up with it, which is not synchronized with the execution of the oil cylinder. According to the feedback from the original manufacturer of the hydraulic directional control cartridge valve, this is the standard model of HydraForce hydraulic directional control cartridge valve. Now the function does not match, so he can only replace it with other model of HydraForce standard parts. Chapin was a little confused. Chapin contacted AAK under the introduction of his friends, and told us the dilemma of the hydraulic directional control cartridge valve sample at present, and asked whether AAK could improve the function of the original hydraulic directional control cartridge valve to match the cylinder execution synchronization? 2 days later, AAK's plan was ready. Chapin paid the development fee the next day and asked for AAK samples. After 40 days, AAK sent the samples of hydraulic directional control cartridge valves. Yesterday, Chapin informed us by email that the test run was successful. After replacing with the AAK hydraulic directional control cartridge valve, the cylinder execution was synchronized and the stability was improved. The prototype has been delivered to the customer. AAK hydraulic directional control cartridge valve has fast response, high shunt accuracy and stability. These 3 advantages are attributed to the optimization of 3 structures based on the original hydraulic directional control cartridge valve. 1. On the main valve sleeve wall of the hydraulic directional control cartridge valve, there are external main oil ports, 2 external load oil ports, locating pins, floating steel balls, and grooves corresponding to the through-hole. The floating steel balls float between the bottom of the locating pins and the grooves. This ensures that the internal load oil port and the external load oil port are always connected, which can realize the static two-way stroke correction of the two load cylinders, and remove the obstacles for synchronization. 2. The spool valve of the hydraulic direction control cartridge valve is sleeved with an inner main oil port and an inner load oil port, and the throttling channel connected with the inner main oil port is on the valve spool. The throttling channel has a fixed orifice and a variable orifice which are connected with each other. The fixed orifice is connected with the inner main oil port. The spool slides back and forth in the spool sleeve to adjust the flow area between the throttle passage and the internal load port. 3. There is also a dynamic variable damping device between the spool and the spool sleeve. When the load suddenly changes, the dynamic variable damping device, under the effect of hydraulic pressure difference, pushes the spool to move, and increases the damping force of the spool when it slides back and forth in the spool sleeve to change the dynamic characteristics of the spool when it slides back and forth in the spool sleeve, reducing the dynamic flow error, and improving the accuracy of diversion. AAK hydraulic directional control cartridge valve, has 1 more function than HydraForce and 3 advantages.

Bill is a purchaser of Manitowoc company in the United States. Two years ago, AAK received an inquiry about hydraulic counterbalance valves from him, and there were few contacts later. Unexpectedly, two years later, we received an email from him consulting about the problems of the hydraulic counterbalance valves. After communication, we learned that a batch of hydraulic counterbalance valves he purchased elsewhere had problems and almost got into a big trouble. Last summer, a crane shipped by their company, the crane winch system lost control during construction and the hook slipped off. Fortunately, there was no one under the hook at that time, otherwise there would be great trouble. According to the analysis of the field engineer, it is considered that the hydraulic counterbalance valve used in the crane winch system is abnormal. After disassembling the hydraulic counterbalance valve, it is found that there is a deviation in the concentricity between the valve spool and the valve seat. The valve spool is affected by large eccentric hydraulic force, so that the hydraulic counterbalance valve lost its function of balance and the hook slipped off. After knowing the reason, Bill contacted the original hydraulic counterbalance valve supplier. The supplier replied that the hydraulic counterbalance valves were indeed within the warranty period, he can replace the abnormal hydraulic counterbalance valves with a new ones, but can not guarantee that each hydraulic counterbalance valve had the same concentricity and could be used for more than 1 year. Bill was worried about the stability of the new hydraulic counterbalance valves. He didn't want to have big trouble and had to find a new hydraulic counterbalance valve manufacturer. In crane hydraulic system, the performance of hydraulic counterbalance valve is the cornerstone of winch system, and the consistency of hydraulic counterbalance valve concentricity is the key. Bill also asked other hydraulic counterbalance valve manufacturers. No factory guarantees that the concentricity of the hydraulic counterbalance valve can be still consistent after 1 year of use. Bill wants to know how about the concentricity of AAK hydraulic counterbalance valves after being used for 1 year. We told Bill that perhaps having a try is the best answer. He can detect the concentricity of AAK hydraulic counterbalance valves in an all-round way. After 15 days, we sent 4 samples of hydraulic counterbalance valves according to his drawings. Seven days later, Bill informed us that the concentricity test data of AAK hydraulic counterbalance valves were indeed more comprehensive than that of his original manufacturer. How to ensure that the concentricity of AAK hydraulic counterbalance valves is still consistent after 1 year of use? For some manufacturers, when processing the components of hydraulic counterbalance valves, there are discrepancies between the specification parameters and design, the standard of normal distribution cannot be reached, there are certain differences in between the structure of components and the concentricity of grooves, which is difficult to detect. AAK has Mahr cylindricity instrument imported from Germany. Through EasyForm software, it can measure each part accurately and quickly, and obtain the measurement results. With the help of computer, the work piece can be quickly adjusted and aligned to improve the measurement efficiency, ensuring the concentricity of each hydraulic counterbalance valve is 100% consistent to reduce wear. More than half a year later, Bill sent an email saying that another two hydraulic valve manufacturers that he recognized, also provided samples of hydraulic counterbalance valves with AAK together last time. All the hydraulic counterbalance valves were retested after 6 months of use. It was found that the concentricity of the hydraulic counterbalance valves from another two manufacturers changed compared with the data before use, but the concentricity of AAK hydraulic counterbalance valves did not change. The boss asked him to list AAK as the most trusted supplier for their hydraulic counterbalance valves. AAK hydraulic counterbalance valves, are sophisticatedly inspected, can be used without no trouble. You are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-counterbalance-valves-aak154

Yaroslav from Russia always likes to find new hydraulic cartridge valve manufacturers for trial orders. When encountering problems, he also asks these hydraulic cartridge valve manufacturers to come to me for help and solutions. Considering Yaroslav's 5-year experience of purchasing from AAK hydraulic cartridge valve manufacturer emotionally, I will truthfully provide assistance to these hydraulic cartridge valve manufacturers in the situation of without wasting my emotions. Yesterday, Yaroslav recommended my WeChat account to the owner of a hydraulic cartridge valve manufacturer in Ningbo China, saying that this manufacturer would like to consult me about hydraulic cartridge valve issues. I estimated he has encountered difficulties on the order placed with this hydraulic cartridge valve manufacturer, and approved this owner’s WeChat friend connection request. The communication is as follows: “Are you Kevin? Yaroslav is my client and he asked me to come to you. I would like to discuss some issues with hydraulic cartridge valves with you.". You are asking for help from someone, but the way is so impolite. What is a discussion? My emotions have also come up, so I replied: “I'm Kevin, but I don't understand hydraulic cartridge valves and I can't discuss it with you. Besides, I'm busy right now. ". The other person replied, still tactlessly and condescendingly. “Aren't you a manufacturer of hydraulic cartridge valves? Why don't you understand?” “I just have a rough understanding about hydraulic cartridge valves, and can only echo what the books say. I haven't reached the level of discussing with others yet! ". He still couldn't see that I was politely refusing, and started leaving messages on his own. "I have been a manufacturer of hydraulic cartridge valves for 5 years, and I don't like to produce trial orders, but there are always clients who ask me to produce trial orders, and they are also very picky about some small problems, other manufacturers of hydraulic cartridge valves are unwilling to do..." etc. He said a lot. I only replied with one sentence and deleted the WeChat account of this hydraulic cartridge valve manufacturer. "You are talking about the trial order of hydraulic cartridge valves. Although I am also a manufacturer of hydraulic cartridge valves, my trial order team is as old as you. I have some experience about how to guide a trial order team well, but regarding how to guide a 5-year hydraulic cartridge valve manufacturer, I am a bit rusty after a long time!". At the same time, I also replied to Yaroslav, “This hydraulic cartridge valve manufacturer is very awesome, and my ability cannot help him.” As the saying goes, “Fish begins to stink at the head.”. How can the entire team be good if the owner of a hydraulic cartridge valve manufacturer has such a rude virtue? I would like to provide a suggestion for young hydraulic cartridge valve manufacturers: first learn to be a person, and then think about how to manage the hydraulic cartridge valve team.
