Ball Valves (True Union)

True union ball valves are the most versatile shut-off and flow-control valve in a plastic piping system — their two union connections let you remove the valve for service without cutting the line. Huiya manufactures pneumatic and manual true union ball valves in all four engineering plastics: UPVC, CPVC, PPH and PVDF, so you can match the valve to your media and temperature, from ambient water to concentrated acids. Built to ANSI, DIN and JIS standards with full-port flow, they suit water treatment, chemical dosing and general process lines.
