Adapters, Valves & Back Rings
Adapters Hole Products offers a wide variety of adapters and transition fittings for butt and socket fusion. Ball Valves Ball valves are used with manifolds to isolate geothermal loop circuits for purging and filling. If a circuit becomes unusable for any reason, it can be shut off and isolated from the rest of the system. Butterfly Valves Butterfly valves can be used for isolating or regulating circulation of water. The butterfly valve is composed of two semicircular plates which are hinged on a common spindle, used to permit flow in one direction or the other.
