LEGEND MODELS T-645 AND S-645 PVC single union ball valves are constructed of ASTM D1784 virgin UPVC resin. They are an excellent alternative to true-union ball valves when only one union is needed. The union end is blocked with a bayonet-style lock, which facilitates ease of repair and/or maintenance. Full ports allow maximum flow and minimum pressure drop or turbulence. Recommended for commercial and industrial applications as a low-cost alternative to true-union ball valves.


Working Pressure, Non-Shock (PSI)
Cold working pressure (CWP): 150 @ 73°F
