CPVC Angle Seat Valve

A CPVC Angle Seat Valve is a type of control valve made from Chlorinated Polyvinyl Chloride (CPVC) material in which the inlet and outlet are positioned at an angle (usually 90°). It is designed to regulate or shut off the flow of liquids in a piping system. The CPVC Angle Seat Valve operates using a seat and piston/actuator mechanism that allows smooth flow control with minimal pressure loss. A CPVC Angle Seat Valve, which is actuated from the rear, can prevent fluid pressure. It is suitable for high-flow work and is installed in lines where conventional ball and other irrigation valves are difficult to assemble and use.

CPVC Angle Seat Valves are widely used in chemical processing, water treatment, industrial fluid handling, and corrosive fluid applications because CPVC provides excellent corrosion resistance, chemical compatibility, and high temperature resistance. These CPVC Angle Seat Valves can be operated manually, pneumatically, or electrically, depending on the application requirements. It is a pneumatically operated, piston-actuated valve with a piston actuator that acts linearly to pull the seal out of its seat.
