3-Way Hydraulic Relay Valve Model 54-M

This 3-Way, single chamber accelerator is hydraulically operated, diaphragm actuated pilot valve that in response to pressure applied to its control chamber, directs flow and pressure between its ports:

•  When pressure is applied to its control chamber, it connects port “0” to “2”.

•  When pressure is released from its control chamber, it connects port “2” to “1”.

This pilot can be used to either relay and accelerate a signal (N.O.), or to reverse and accelerate a signal (N.C.).
