High Platform Ball Valve
Use ISO5211 standard platform design, without connection bracket make the actuator easily assembled.Blow-out Proof Stem design
1. use anti-blow out stem design.
2. The first stage sealed, tapered stem seals effectively prevent stem rotation in the process of media leaks, and unusual boost in the state, also effective to prevent leakage.
3. The second stage seal, a combination of V-shaped packing is compressed in the expansion to either side, thus preventing leakage.
4. Release the preload of disc spring, automatic fill packing and stem seal wear.
5. Use stem nut compress all of the stem seal system, to prevent leakage.
6. Only the back pad fixed stem nut to prevent its release.Manual locking design
