Relieving Pressure Reducing Regulators
Relieving Pressure Reducing Regulators can bleed or vent pressure when the downstream pressure exceeds the setpoint, even in a no-flow condition. Typically, this happens via a relief valve in the center of the diaphragm and pintle assembly. The relief valve will then stay open until the pressure levels are back to normal and return to safe levels.
There are several pressure regulator applications that are suitable for a pressure relieving regulator. A relieving pressure reducing regulator should only be used in instances where the excess pressure can be safely released into the atmosphere.
