WCB LCB CF8 CF8M Material Trunnion Ball Valve DN 15-250 PN20-260

Urgent grease injection device

According to customers' requirement the trunnion ball valves made by our company are provided with devices for urgent grease injection,which are on both the stem and seat for the trunnion ball valves of DN>150mm(NPS6),and in the body cavity for the valve of DN>125mm.When the O ring of stem or the body seat ring is damaged due to accident,the medium leakage between body and stem can be preventd by injecting the sealing grease throng the device.

Double-Block and bleed functions

In general,our valve trunnion ball valve features the front ball sealing design structure.Each seat of the ball valve can separately cut of the medium at both inlet and outlet of the valve to realize double-block functions.When the ball valve is closed,body cavity and two of the body ends can be blocked with each other even if both the inlet and outlet are under pressure,when the medium left in the body cavity might be bled through the relif valve.
