Feature:
1. The design of valve body is long-necked to meet requirement of pipe insulation and help to install the drive.
2. Valve plate sealing surface for a special polished, reduce the opening and closing torque, extended the life of valve seat; the valve sealing up to gas seal level; hollow board design to withstand pressure; weight are light and flow resistance are small.
3. The outside rubber edge of valve body is protruding;the body have a long structure, can replace the flange gasket.
4. It can be either used through bolts or be connected in side bolts, which will help to replace and repair pipes.
5. Connection of plate and shaft are no pin to achieve the best match and the opening torque transmission, and reduce the leakage point.
6. Can be configured according to user manual, electric, pneumatic and other different operator.
7. Products certified by API 609 and NSF.
