Platform design uses the standard, without connecting bracket and the shaft sleeve, so that the actuator installation easier
A valve stem, leak proof design
1, with blowout proof stem design
2, the first stage seal, tapered stem sealing pad effectively prevent leakage of mediumin the valve stem rotation process, and in abnormal pressure condition, also can prevent the leakage effectively
3, the second stage seal, a group of V type combined filler after being compressed to the two sides to expand, thereby preventing leakage
4 preload, the release of the dish shaped spring, abrasion of the sealing padautomatic compensation and the valve stem packing
5, the use of sealing system of stem nut pressing all stem, prevent leakage
6, the stopping pad fixed stem nut, preventing its release
Two, a manual locking design
Switch lock risk prevent accidental mistaken operation maintain valve position existingwhen necessary. Valve platform and handle with a lock, used padlock the valve in the closed position or the opening and locking
