10691 Series Relief & Back Pressure Valve

Brand: Watson McDaniel

The 10691 Series Back Pressure & Relief Valves relieve upstream pressure in a variety of processes. The 10691 Series has a soft elastomeric disc for tight shut-off. These valves automatically maintain desired maximum pressure in a vessel or system by relieving excess pressure into lower pressure return line or to atmosphere. 

Ideally suited for use as pump bypass control valve by maintaining constant pump discharge pressures. Used as a continuously operating valve or for protection against intermittent overpressure conditions.
