Drain valve GARDENA 2760-20

The drainage valve from GARDENA, a GARDENA Sprinkler System component, protects the underground system from frost damage. This protection is ensured by automatic draining when the system is shut down - the valve opens when the water pressure in the system drops below approximately 0.2 bar. Drainage valves should be installed at the lowest point of the irrigation system and for safe draining in flushed coarse gravel. It has a 3/4" thread.
