Decisions depend on valve design and application. Often, the malfunction of a solenoid valve can be attributed to easy to fix issues, such as dirt in the valve (80% of the cases). With the controller in the OFF position, simply remove the wires on the solenoid and unscrew it from the valve. This article will address how maintenance of such a small component can be worthwhile and the difference upkeep can make to the system; when to repair vs replace; … A s with any mechanical apparatus, proper and proactive maintenance and care of solenoid valves can extend their lives and ensure predictable operation. Troubleshooting How the Valve Works It is easier to troubleshoot valves if you know a little about how the valve works. Solenoid valve troubleshooting: the most common failure modes.

If you already have a replacement orbit solenoid, you could try unscrewing the adapter from the old solenoid to use with the new. The following is a quick lesson on how electronic solenoid valves operate. When the plunger moves upward, a small hole Do NOT try to test the controller by using a wire to create a short-circuit “spark” between the terminals!
