Hardie 2" Valve Solenoid Replacement: Irritrol Parts Compatibility

Finding the Right Solenoid

Hardie was acquired by Irritrol. The 2" Hardie valves have used the same solenoid for decades. Current Irritrol valves use the identical solenoid.

Solution

Take the broken solenoid to any irrigation supply store. Ask for a solenoid for an old Hardie valve — they'll match it to the current Irritrol part. Generic solenoids (like Champion RK-811) often don't fit due to thread or plunger differences.
