High Flow Reversing Relay Model 2500A

The Model 2500A Bias Reversing Relay provides an outlet pressure that decreases in direct proportion to increases in input signal. The input signal that acts on the Diaphragm Assembly opposes the Range Spring force and closes the Supply Valve to decrease output pressure, according to the formula (Po = K - Ps); where Po is output pressure, K is the spring constant, set by the screw, and Ps is signal pressure. The M2500A pneumatic relay delivers this performance at a flow capacity of 255 m³/HR (150 SCFM), to provide fast response and tight control over your application.
