Forged Trunnion Ball Valve

FUWEI valve has very professional experience in manufacturing and supplying of Forged Steel Trunnion Ball Valve well use in different industries.

The trunnion ball valves manufactured by FUWEI valve have the obturator bounded by trunnion which prevents axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cavity relief in case of overpressure in body cavity; the valve can be selected for a wide range of applications with no specific limits to size and pressure.
