Maintenance – Fluid Solenoid Valve

Shutdown Procedure

WARNING

ELECTRIC SHOCK HAZARD

To reduce the risk of serious injury,
including electric shock or splashing fluid
in the eyes or on the skin, always follow

this procedure before servicing any part of the Fluid
Commander system and before checking for loose
or shorted wires.

1.

Turn off the control and unplug it.

2.

Shut off the power to the pump(s)

3.

Relieve fluid pressure as instructed in your pump
and/or dispensing valve manual(s).

To Clean the Solenoid Valve

The solenoid valve is normally closed. Foreign matter
could hold the valve open, preventing it from stopping
the fluid flow. If that happens, follow the procedure
below.

1.

Follow the 

Shutdown Procedure

, above. Be sure

to open the dispensing valve controlled by the
solenoid valve to relieve line pressure.

2.

Close the shutoff valve ahead of the solenoid
valve.

3.

Unscrew the nut, remove the operator, and un-
screw the piston from the body. See Fig. 4.

4.

Clean the parts and the seat in the body. Blow air
into the body to clear the fluid passageways.

5.

Reassemble the valve and dispense fluid to see if
the open condition has been corrected. If it has
not, replace the solenoid valve.

NOTE:

 Dispense fluid at the dispensing valve, con-

trolled by the cleaned or replaced solenoid valve, until
all air is purged from the system.
