Pressure Regulating Valves

George Fischer offers three types of pressure regulating valve designs that either reduce, retain or relieve pressure. These valves provide highly accurate and stable pressure control irrespective of fluctuations of inlet pressure or changes in flow demand. The valve body works by balancing an adjustable spring force that pushes downward onto a diaphragm against the force of the process fluid pushing upward.

Maintains precise pressure as low as 7-150 psi Adjusted by an adjusting screw and secured with a locknut Mechanic valve parts are isolated from the process fluid
