In a self operated pressure regulator, as downstream system pressure decreases the spring force overcomes the force of the gas acting on the effective area of the diaphragm and the valve opens increasing flow into the system.
How does a pressure regulating valve work?
It is often referred to as a pressure regulator. The valve simply uses spring pressure against a diaphragm to open the valve. ... When the outlet pressure drops below the set point of the valve, the spring pressure overcomes the outlet pressure and forces the valve stem downward, opening the valve.
How does a self regulating PCV work?
Structure of a self actuated pressure control valve
When the pressure downstream to control valve increases beyond setpoint, process fluid exerts increased pressure on the diaphragm thus closing the valve. Closing of the valve stops process flow thus reducing the valve downstream pressure back to setpoint level.
