Antelco Purple Back Valve, 1/2" barbs

For simple control of water flow in low-pressure irrigation systems, it doesn’t get much easier than the simple "on/off" functionality offered by the Vari-Flow Valve and Purple Back Valve. Intended for connection to both inlet and outlet tubes, the 1/2" barbed Purple Back Valve and 1/4" barbed Vari-Flow Valve can each handle up to 45 psi.
