Pneumatic Three-piece High Pressure Ball Valve
Introduction:
Pneumatic three-piece high-pressure ball valve can be used in two-way fluid occasions. The valve port size is large, allowing a large flow to pass through, and can achieve tight cut-off, long service life, and small operating torque.
Features:
1. Ball valve stem adopts anti-blowout design.
2. Stage sealing, the tapered valve stem gasket can effectively prevent the leakage of the medium during the rotation of the valve stem, and can also effectively prevent leakage in the abnormal boost state.
3. Stage sealing, a group of V-shaped composite packing expands to both sides after being compressed, thus preventing leakage.
4. Release the pre-tightening force of the disc spring, and automatically compensate for the wear of the packing and the valve stem gasket.
5. Use the stem nut to compress all stem sealing systems to prevent leakage.
6. The anti-return pad fixes the stem nut to prevent it from loosening.
