The Apollo ExpansionPEX 1/2 in. Brass PEX-A Barb Ball Valve with Drain and mounting pad is simple to install and provides flow control through an anti-stick and smooth operating quarter turn lever handle. The quarter turn， single lever control allows for simple control of water flow in hydronic and potable water systems and the side vent allows for the expulsion of air or water for testing， repair or weatherization situations. Also capable of integration into hydronic heating systems， Apollo ExpansionPEX valves must be secured into place Apollo ExpansionPEX sleeves or comparable expansion-type sleeve or ring (all sold separately). The Apollo ExpansionPEX system is a comprehensive piping system comprised of lead free brass fittings， poly alloy fittings， manifolds， valves， fasteners， tools and tubing designed for implementation in water delivery systems， simple or complex. A cold-expansion tool (sold separately) is required for installation.
