CPVC Compact Ball Valve
A CPVC Compact Ball Valve is a quarter-turn shut-off valve made from Chlorinated Polyvinyl Chloride (CPVC) material, designed with a compact body structure to control or stop the flow of liquids in piping systems. It uses a rotating ball with a bore (hole) inside. When the handle is turned 90 degrees, the valve either allows fluid to pass or completely stops the flow.
The CPVC Compact Ball Valve is a lightweight and space-saving flow control valve designed for on/off service in piping systems handling corrosive or high-temperature fluids. This CPVC Compact Ball Valve offers excellent chemical resistance and thermal stability. It features a full-port design for minimal flow restriction and is ideal for compact installations where space is limited. The simple quarter-turn operation ensures quick and reliable shutoff in industrial, chemical, and water treatment applications.
