Two-Way 2-Position Valve and Coil
These valves allow for free flow in one direction (from the bottom port to the side ports) at all times and controlled flow
in the opposite direction until the solenoid coil is energized
.
Troubleshoot and repair these valves as follows:
1.
If the valve does not shift, check and repair (if necessary) the following items:
– The valve “hot” wire and ground wire
– The switch controlling the valve.
– The supplied voltage.
– The continuity of the control valve coil.
– A bent valve stem. Replace valve.
– Any debris in the valve cartridge.
– Check for debris by energizing the valve without starting the motor and listening for the valve to shift (a
definite “Click” is heard when the valve in energized).
– If the valve does not shift, remove the cartridge from the valve body.
– Blow compressed air through the cartridge in both directions while holding the plunger off its seat. Use a
blunt object inserted through bottom of cartridge to move plunger. It will help to have the “body” filter
removed.
