Hydroswitch Valve

The Hydroswitch valve is a 3-way solenoid valve controlled by the output from the
Hydroswitch. It is used to drive the HWM mechanical actuator.

The Hydroswitch valve body is labelled (red and green dots) to assist in identifying the
ports during installation.

Cable

(from Hydroswitch)
