Gardena Pipeline And Sprinklersystem Threaded Drain Valve

The gardena pipeline and sprinklersystem threaded drain valve is an essential component designed to protect underground irrigation systems from frost damage through automatic drainage. When the system is taken out of operation, this drain valve opens automatically when water pressure drops below approximately 0.2 Bar, allowing complete drainage of the pipework. For effective winter protection, the drain valve should be installed at the lowest point of your irrigation system where water naturally collects. Professional installation requires the valve to be positioned within a pack of washed coarse gravel, which ensures reliable drainage and prevents soil ingress that could compromise the automatic drainage function. The valve features a 3 4-inch thread connection, making it compatible with standard gardena sprinkler system pipework and fittings. This automatic drainage system is ideal for garden irrigation installations, landscape contractors working on commercial grounds maintenance, and horticultural applications where underground pipework must remain frost-free during winter months. Features and benefits: automatic operation prevents manual draining and reduces winter maintenance opens when pressure drops below 0.2 Bar for reliable frost protection 3 4-inch threaded connection for straightforward installation designed specifically for lowest-point installation in underground systems specifications: thread size: 3 4 operating pressure: opens below 0.2 Bar
