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.).
