STATIM Solenoid Exhaust Valve maintenance

Several STATIM cycle faults can result from a solenoid exhaust valve that is stuck open or closed, so annual maintenance is key.

There are two simple methods for removing the plunger tube without the special solenoid plunger wrench.

First, and very easy:

You can use two nuts tightened on the plunger, and then loosen the plunger with a wrench on the bottom nut.

Remove the nut then the yoke and coil from the solenoid plunger valve.
Then screw on two nuts on the plunger tube. (should be 11/16 OD – 3/8 ID at 2/64 thread)

Tighten the top nut, then loosen the plunger tube with the wrench on the bottom nut in the opposite direction.

Two nuts can be used to loosen a Solenoid exhaust valve plunger tube.

Alternatively, you can use two wrenches:

Tightening the top nut until with one wrench until you can loosen the plunger by turning the yoke of the valve the opposite direction.

See my below video for how to open the plunger tube in under 30 seconds for STATIM solenoid exhaust valve maintenance.

What to expect inside:

Solenoid exhaust valve parts
Old solenoid plunger, spring, bronze disk and flange seal will patina with time and need to be cleaned or replaced annually.

Plungers can be cleaned, but eventually work better when replaced.

Found an obstruction?

Small wires or particles could stick in the valve, preventing it from closing or opening.
Cleaned and ready for a new plunger repair kit.
