TFV Series irrigation solenoid valves are designed and intended for use in turf irrigation applications only (residential, commercial, and agricultural). While these valves may operate in applications other than they are intended, the AGI warranty will not apply for those uses. It is built with a high strength, long lasting natural rubber diaphragm and a rugged glass-reinforced nylon construction. Its in line maintenance feature means there's no need to remove the valve from the water line to service it.
