Structural features 1. Integral welded ball valve, no external leakage.
2. The valve seat is composed of PTFE sealing ring and spring, which has strong adaptability to the change of pressure and temperature, and will not produce any leakage in the use range.
3. The machining process of the ball is tracked and detected by the advanced computer detector, and the processing density of the sphere is high.
4. The sealing ring is made of c-ptfe with 20% carbon to ensure no leakage.
