Gardena Pipeline Drain Valve

Description

Gardena Pipeline Drain Valve

The Gardena drain valve, an element of the Gardena Sprinklersystem, protects the system from damage that may occur during frost if the system is installed underground. This occurs through automatic drainage when the system is shut down; the valve opens when the water pressure in the system is below approx. 0.2 bars. The drain valves must be installed at the lowest point of the irrigation system and installed in a coarse gravel pack to ensure safe drainage. It has a 3/4 "thread.
