J-VALVES
Metal sealing structure: Featuring a metal-to-metal hard seal design, it is resistant to high temperature and wear, applicable to harsh media with high temperature, high pressure and solid particles.
Trunnion ball design: The ball is fixedly supported by the upper and lower valve stems, ensuring stable operating torque and reliable sealing performance under high pressure difference conditions.
Electric actuator: Equipped with an intelligent electric actuator, it supports remote control, local operation and fault self-diagnosis functions to realize automatic process control.
Flange connection: Adopting RF (Raised Face) or RTJ (Ring Type Joint) flange connection in compliance with ASME B16.5 standard, it guarantees sealing reliability in high-pressure environments.
Fire-safe design: In line with API 607 standard, the metal sealing structure can still maintain sealing performance in case of fire to prevent medium leakage.
Anti-static device: Built-in anti-static device effectively prevents electrostatic accumulation and reduces the risk of fire and explosion.
Blowout-proof stem design: The valve stem is designed with a blowout-proof structure to ensure the safety of operators and equipment.
High-reliability bearings: The upper and lower support bearings are made of high-strength alloy materials, featuring high load-bearing capacity and long service life.
