3-Way Accelerator Model 54

This 3-Way, single chamber accelerator is a hydraulically operated, diaphragm actuated, pilot 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.).
