The IS Solenoid Valve is used to control the diesel machine’s pressure circuit based upon the outputs of
the Diesel Machine Monitor.
The I.S. Solenoid Valve can be mounted in any suitable location. The pneumatic connections are:
Ports 1 and 2 are normally connected when the solenoid is energised.
Ports 1 to 3 (the vent port) are connected when the valve is de-energised.
The valve should be connected so that the pressure is released from the downstream side of the valve
when de energised.
