111531 WM-147-F Relay Valve

Williams Controls WM-147-F Relay Valve 111531. The normally open WM147 relays are installed in control circuits that can provide sufficient control pressures for closing the valves. These relay valves are used in industrial and vehicular applications that require a normally open relay with average flow capacity. The three-way models are frequently used as reversing relays for two speed axles. Three way models are also used with a two-position control valve in applications where a four-way function is desired. The normally open, two-way relays are often installed as circuit controls for driveline retarders.
