Pain Points and Proposal
1. Jam: Under pure, high-pressure, high-temperature, degreased, and dry oxygen/nitrogen/hydrogen service conditions, metal to metal "bite" (micro-welding phenomenon) easily occurs between parts; These phenomena occur on these parts: ball, seat, bearings, bushings, stem, bottom shaft, etc.
2. Internal Leakage:The valve passed factory accetance pressure testing but leakage occurs while running online.
3. After long-term using under high pressure alternating, the body seal gasket is prone to leakage.
1.Zero leakage under long-term pressure holding.
2.Sealing mathematical model
3.Reliability engineering
4.Quantitative compression technology to ensure that the torque fluctuation of each product does not exceed 20%
5. Interchangeable of ball seats; stable torque ensures long service life
6. Anti-bite alloy coating
7. Strongly rigid valve seat design to prevent jamming caused by valve seat distortion.
