Feature

(1)Urgent grease injection device

The trunnion ball valves (≥DN150) are provided with devices for urgent grease injection, when fire breaks out or accident happens, the medium leakage between the body and stem can be prevented by injecting 50℃ thaw lesssealing grease to the seat and stem through the device. Inside the valve there is a check valve for back up use.

(2)Double-block and bleed functions

Each seat of the trunnion mounted ball valve can separately cut off the medium at both inlet and outlet of the valveto 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 relief valve.

(3)Self-relief in the body cavity

As the liquid medium left in the body cavity gasifies due to increased temperature, the pressure in the body cavity becomes abnormally higher, when the medium itself in the cavity would propel the seat and self-relieves the pressure to ensure the safety of valve.

(4)Fire safe design

Our ball valve designed with double O-ring together with graphite winding pads, when the O-ring damaged by fire, the graphite pad can prevent the body medium leak out.
