(5PK) ERA Sch 80 PVC 3/4 Inch True Union Ball Check Valve, Socket Connection

Schedule 80 ball check valves have a spherical ball inside the valve body which works as a check to allow flow one way and close off to prevent back-flow. These only have a ball, no spring, so must be used in an upflow position to work properly. The true union design eases valve removal from piping systems without having to break down the pipe.

• Efficient One-Way Flow Control: This Schedule 80 ball check valve features a spherical ball inside the valve body, designed to allow flow in one way and prevent back-flow, ensuring optimal fluid flow control for various applications.
• Durable PVC Construction: The valve body, ball, and end are made from high-quality PVC, offering resistance to corrosion, chemicals, and weathering for long-lasting performance in demanding environments.
• Reliable Sealing Performance: Equipped with EPDM O-rings and seat seals, this valve provides a tight seal to prevent leaks and maintain a consistent, efficient flow, even in tough conditions.
• Upflow Installation Requirement: This valve operates best when installed in an upflow position. Due to the lack of a spring, the ball check mechanism relies on gravity to close off and prevent back-flow when used properly.
