Back Pressure Regulator Symbol

What is a Back Pressure Regulator?

A back pressure regulator (BPR) is a type of valve that maintains a defined pressure upstream of its inlet. When fluid pressure within the BPR’s inlet exceeds a setpoint, the regulator opens up to remove the excess pressure.

Difference Between a Pressure Regulator and a Back Pressure Regulator

A pressure regulator is designed to reduce the incoming pressure to a specific lower pressure at the outlet, maintaining the downstream pressure. A back pressure regulator works in the opposite direction, regulating pressure coming through the inlet by opening up only as much as necessary to maintain the desired upstream pressure.

What is the Back Pressure Regulator P&ID Symbol?

The back pressure regulator symbol P&ID is a graphical representation of the valve, used to give an easy indication of the device’s location so that engineers don’t need to perform a physical inspection.

In process flow diagrams, back pressure regulators are depicted using a circular symbol containing an arrow that points upward.
