Pressure Control Valves vs Pressure Regulators: What is the Difference & Where Are They Used?

April, 3, 2012

pressure control valves and pressure regulators

The sales team at Pneumadyne is often asked about the differences between Pressure Control Valves and Pressure Regulators.  Not understanding the difference between these valves can result in installation problems within a pneumatic system.

The Difference

Pressure Control Valves are ideal for applications requiring a reduced pressure to a cylinder whereas Pressure Regulators are used to maintain a pre-set downstream pressure.

Proper Installation

The Pressure Control Valve is designed for use between a valve output and a cylinder or other volume, where the reduced pressure is desired.  A high volume check valve is built in to allow for rapid reverse flow.  It is also ideal for continuous flow applications where reverse flow is not required.

A Pressure Regulator is installed before a valve to allow a pre-set pressure to flow downstream to a cylinder or other volume.  Placing the regulator before the valve in a pneumatic system ensures that the regulator will not be cycled or exposed to reverse flow.
