WPT-3 is specially designed for high-pressure valve testing. It adopts a 500kN hydraulic pressure system (accuracy ±1%), supports 4 independent testing stations for DN50-DN800 valves, and covers 0-150MPa water pressure/air pressure testing. Equipped with a PLC intelligent control system and a 10-inch touch screen, it automatically completes shell strength (1.5PN) and seal leakage (1.1PN) tests, and complies with ASME B16.34 and API 598 international standards. It is the core testing equipment for petrochemical, nuclear power, and high-pressure pipeline projects.
