Trunnion Ball Valve Side Entry Split Body

Valves suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining.

Trunnion ball valves have the obturator bounded by trunnions which do not allow 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 sizes and pressures.
