Drip valve solenoids are available for replacing old solenoids on existing valves in your drip irrigation system. Frequently, when a valve fails to open, it is caused by a bad solenoid, and can be fixed by simply removing and replacing the old solenoid. This is a faster, easier, and less expensive alternative to replacing the entire valve. We offer a wide selection of solenoids for use with many different valves. It is important to select the correct solenoid to fit your valve, so be sure to check thread types, voltages, and any information about usage with specific valve models.
