Pain Points and Proposal
1. Jam: Under high-pressure gas 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.Anti-bite alloy coating. Strongly rigid valve seat design to prevent jamming caused by valve seat distortion.
2.Zero leakage under long-term pressure holding.
3.Quantitative compression technology to ensure that the torque fluctuation of each product does not exceed 20%
4. Interchangeable of ball seats; stable torque ensures long service life
