Forged Trunnion Mounted Ball Valve

Trunnion ball valves 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; these valves can be selected for a wide range of applications with no specific limits to all sizes and pressures.
