Pain Points and Proposal
1. External Leakage: packing wear due to frequent opening/closing without any compensation, finally external leakage occur.
2. Jamming:
① soft material seat wears due to frequent high-speed operation, making sealing surfaces rough and causing jam.
② valve bearings waers due to long-term rapid cycling, increasing surface roughness and get jamming.
3. Internal Leakage:
Soft seat wears on surfaces due to frequent high-speed operation, results in internal leakage.
1. Self-Adjusting Packing:
Precision wear compensation formula maintains seal integrity.
2. Exclusive Hardened Bearings:
Engineered for enhanced durability under heavy use.
3. Ultra-Low Stress Sealing Surfaces:Minimizes wear on critical sealing components.
4. Constant Light-Touch Compensatio
