Test

Yongjia Dalunwei Valve Co., Ltd is committed to producing high-quality ball valves that meet the rigorous standards set by the American Petroleum Institute.

the mid-cavity pressure relief test of a ball valve is a key test to ensure that the ball valve can effectively prevent medium leakage when it is closed. It helps to verify its sealing performance, thereby ensuring the safety and reliability of the ball valve in practical applications.

 the anti-static test for ball valves is a critical evaluation process that ensures the valves are equipped to handle static electricity safely, thereby reducing the risk of ignition or explosion in environments where flammable or combustible materials are present. By meeting the requirements of the anti-static test, ball valves can provide a higher level of safety and reliability in industries where the management of static electricity is essential for preventing potential hazards.

 the performance test of the pneumatic hard-sealed ball valve is a comprehensive evaluation of its ability to withstand water and air pressure, maintain a secure seal, and deliver reliable performance in demanding industrial environments. The Q647Y model from Yongjia Dalunwei Valve Co., Ltd exemplifies the company's commitment to producing high-quality valves that meet the stringent requirements of modern industrial applications. With its robust design, high-pressure capacity, and versatile size options, the pneumatic hard-sealed ball valve is a reliable choice for industries seeking durable and efficient flow control solutions

Ball valve spark test is a testing method used to detect the sealing performance of ball valves. During the test, the sealing performance of the ball valve is judged by applying voltage when the ball valve is closed to generate electric sparks, and then observing whether the ball valve can effectively prevent the penetration of electric sparks. This testing method can help ensure that the ball valve can effectively prevent the leakage of fluid or gas when it is closed, ensuring the safety and reliability of the ball valve.

Low-temperature testing of ball valves refers to testing the performance of ball valves in low-temperature environments. Under low temperature conditions, the performance and tightness of materials may change, so low temperature testing of ball valves can evaluate their reliability and stability in low temperature environments. This test usually involves placing the ball valve in a low-temperature environment and then testing its sealing performance, operating performance, material properties and other indicators. This helps ensure that the ball valve will function properly in low temperature environments and will not develop leaks or other problems.

FET microleakage testing is a testing method used to detect microleakage in valves. FET is the abbreviation of "Field Effect Transistor", which is an electronic component used to measure small currents. In the FET micro-leakage test of the valve, the FET sensor is installed at the valve seal. When the valve is closed, the FET sensor can detect small current changes to determine whether there is a small leak in the valve. This testing method can help ensure the sealing performance of the valve and prevent leakage from occurring.

Yongjia Dalunwei Valve Co., Ltd's utilization of ultrasonic thickness measurement aligns with industry standards, demonstrating the company's commitment to ensuring the quality, safety, and reliability of its ball valves. This advanced testing method not only meets the rigorous requirements set forth by industry regulations but also underscores the company's dedication to employing cutting-edge technology to assess the integrity of its products. 

MT testing of ball valves can help detect cracks and defects, evaluate the quality and reliability of ball valves, prevent ball valve failures, and ensure the safe operation of ball valves.

the PT test performed on the ball valve can help ensure the sealing performance and pressure resistance of the ball valve and ensure the safe operation of the system. It is also an important means to evaluate the quality and reliability of the ball valve
