GROVE B7

Valves

The B7 valve identifies the side-entry ball valve ASME Class 2500. Because of the high pressure and strong force involved, material selection is carried out by paying particular attention to the antiextrusion features of the gaskets and to the resistance of the ball and stem materials.
