Double Union Pvc Ball Valve By Flexitech Industries

PVC (PolyVinyl Chloride) ball valves are widely used plastic shut off valves. The valve contains a rotary ball with a bore at the center. By rotating the ball a quarter-turn, the bore can be aligned inline or perpendicular to the piping to open or block the media's flow. PVC valves are durable, cost-effective, and used for a wide variety of media, including water, air, corrosive chemicals, acids, and bases. Compared to brass or stainless-steel ball valves, they have lower temperature and pressure resistance and lower mechanical strength. They are available with different piping connections, such as solvent sockets (glue connection), different flange types, or pipe threads. Double union, or true union valves, have separate pipe connection ends fixed to the valve body by a threaded connection. A true union ball valve with sockets and a manual handle is the most common. The valve can be easily removed for replacement, inspection, and cleaning. To learn more about these versatile valves read our introduction to ball valves.
