The Yongjia Duojia Hydraulic Equipment Co., Ltd. independently developed safety valve test bench is mainly used for verifying the opening pressure and sealing performance of safety valves, and can also verify the return seat pressure. It boasts excellent sealing performance, cleanliness without pollution, rapid pressure increase speed, and high control accuracy. The pressure calibration range using gas as the medium is 0-32MPa, with calibration accuracy up to 0.4 grade, meeting the requirements for inspection of various specifications of valves.

Performance Features

Performance test for safety valve with flange connection type, including sealing pressure, adjustment, opening, and return seat pressure

2. The flange face is sealed using a gripper clamp, with the clamping gripper securing the back of the flange for work testing. The system is stable, operation is simple, calibration accuracy is high, readings are precise, and work efficiency is high. 3. The system is built-in with an automatic pressure adjustment device for increasing test pressure.

4. Test medium is air, nitrogen, or water; users can choose as preferred.

5. The system is equipped with a safety locking device and a shutdown pressure retention feature.

6. Configurable computer system for collecting pressure data, storing, and printing test results.
