Due to the tariff war initiated by the Trump administration, all of our American customers have ceased inquiries, orders, production, and shipments, resulting in orders being put on hold. The customers stated that they are not planning to cancel the orders, but rather to pause for a while, hoping that the situation can change and wait for a better solution before shipping. AAK has been committed to producing and exporting high-quality hydraulic threaded screw-in cartridge valves that benchmark international first-line brands. Europe and America are our main markets, with the United States accounting for over 50% of AAK's export value. The tariff war has a significant impact on Chinese hydraulic cartridge valve manufacturer AAK. Fortunately, AAK has accumulated over 15 years of experience in the foreign trade export industry, and its customers in countries other than the United States, especially Russia and India, are increasing year by year. After Western brands withdrew from the Russian market, Chinese mechanical components filled the gap. The performance in the field of construction machinery is particularly outstanding, with Chinese brands' market share in Russia jumping from 43% in 2023 to 66% in 2024. As a core component of construction machinery, the export share of hydraulic threaded screw-in cartridge valves has grown synchronously. China's exports of construction machinery products (including supporting components) to India will maintain double-digit growth in 2025, especially in categories such as cranes and excavators. Chinese brands will quickly replace European and American products through their cost-effectiveness advantages. The demand for hydraulic threaded screw-in cartridge valves as core transmission components is increasing synchronously. We have also received multiple trial orders from new customers in Russia and India recently. It is within reach to turn these new customers into long-term repeat customers with AAK's excellent quality and high-quality service. No matter how policies and international situations change, AAK's good quality, good price, and good service will always be the first pursuit of customers. Although Chinese hydraulic cartridge valve manufacturer AAK has temporarily encountered some obstacles in the US market, its core advantages are universal and popular in any country. In the long run, we believe that our overall development will not be affected, and may even be better. AAK HYDRAULIC VALVES (846) 2025-04-23

2 months ago in early February, AAK customized a PV72-30AM Proportional Valve Assembly for a European customer. The valve assembly includes a HydraForce solenoid operated, pressure compensated, spool type, normally closed, proportional priority flow control valve PV72-30AM-0-N-12DG, and a HydraForce CV08 series Check Valve, assembled to an aluminum block. This is just very similar to a valve and block assembly that we shipped to a customer in Russia before, and we finished it in 15 days and a/f’d it to customer by end February. 2 weeks ago in early April, we received email from customer that they are happy with test result and are willing to place order for another batch – part of them to be shipped by air and remaining to be shipped by railway or sea. This batch is now in production and will be ready by end April. PV72-30 proportional valve is one of our best sellers and is usually in stock shortage. Last week, we just shipped a test order to a customer in Belarus. There are several hydraulic cartridge valve manufacturers in Ningbo China who can offer PV72-30 model, but AAK is the top choice in combining the price, quality, fast delivery and efficient customizing service.

Chinese Hydraulic Screw-in Cartridge valve manufacturer AAK often receives various questions from overseas customers, some of which even come from college students conducting academic research. Today, we will once again introduce the main materials used for seals in hydraulic screw-in cartridge valves, as well as their respective characteristics: 1. Rubber Sealing Materials 1) Nitrile rubber (NBR) - Excellent oil resistance, suitable for conventional hydraulic oil environments, with a working temperature range of -40 ℃ to+120 ℃. - Mainly used in static sealing scenarios, such as O-rings and some combination seals 2) Fluororubber (FKM) - High temperature resistance (up to 200 ℃), chemical corrosion resistance, suitable for hydraulic oil containing phosphate esters or highly corrosive media. - Commonly used in high-pressure systems or extreme temperature environments. 3) Silicone rubber (VMQ) - Outstanding cold resistance (-70 ℃ to+200 ℃), but low mechanical strength, only suitable for static sealing 2. Polymer Sealing Materials 1) Polytetrafluoroethylene (PTFE) - Extremely low friction coefficient, good self-lubricating properties, strong corrosion resistance, suitable for high-speed or chemically corrosive environments. - Often used as a filling material in conjunction with rubber, or in combination with seals (such as Glay rings, seals). 2) Polyurethane (PU) - High wear resistance and anti extrusion strength, suitable for high- pressure reciprocating motion seals (such as Y-shaped rings, U-shaped rings), working temperature -30 ℃ to+100 ℃. 3) Nylon (PA) - Oil resistant and wear-resistant, used for non direct sealing components such as guide rings and support rings, with a working temperature of -40 ℃ to+120 ℃. 3. Metal Sealing Materials Stainless steel/copper alloy - Used for extreme high pressure (>32MPa) or high temperature (>450 ℃) scenarios, achieving metal to metal sealing through precision machining. 4. Composite Sealing Materials Clip on rubber+rubber (lace ring) or PTFE+rubber (Glay ring/Steller seal) - Combining the elasticity of rubber with the wear resistance of PTFE/sandwich material, suitable for high-pressure dynamic sealing (such as valve spool and valve cage). Selection Suggestions - Normal working conditions: Priority should be given to using nitrile rubber or polyurethane. - High temperature/corrosive environment: Fluorine rubber or PTFE composite materials are better. - Ultra high pressure scenario: requires metal seals or combined sealing structures.

Manufacture High-Quality, Customizable Plastic Or Acrylic (PMMA) Round Bubble Level Vials At A Low Price By Aohong Co. Round level vials, also known as circular level vials, are spirit levels utilized to determine the levelness of a surface, distinguished by their circular or dome-like shape and consisting of a slightly concave surface filled with liquid and a bubble. Constructed from plastic, glass, or metal, these vials are chosen for their durability, cost-effectiveness, and precision, catering to varied applications and environments across numerous industries, such as construction and carpentry, where precise horizontal alignment is vital. Angular value The accuracy of a bubble level vial, or its angular value, pertains to the inclination of the bubble during movement. For round level vials, accuracy is defined by the bubble’s inclination as it moves 2mm from the center along any radial direction. In contrast, for elongated bubble vials, accuracy refers to the bubble’s inclination when it shifts 2mm along the axial direction.

Tubular level vials, also known as bubble or spirit levels, are used in construction and photography to ensure surface alignment Tubular level vials, also known as bubble vials or spirit levels, are essential tools used across various industries like construction, photography, and aviation to determine the horizontality or verticality of a surface. Valued for their simplicity and precision, they are crucial in applications where accuracy is paramount, providing essential functionality to ensure surfaces are perfectly level or plumb across various professional fields and applications. Basic Structure and Operation Tube Shape: They are typically in a tube shape, which is where their name derives. The tube is filled with a liquid, usually a type of alcohol, leaving a small bubble. Bubble Movement: When the vial is placed on a surface, the bubble moves within the liquid. The positioning of this bubble indicates whether the surface is level. Graduations: Some tubular vials have graduations or lines to help indicate how off-level a surface is. The spirit bubble level vials can be made from various materials like plastic, glass, or metal, each providing different durability and clarity.
