PVC Double Union Ball Check Valve
PVC double union ball check valve uses a free-floating PVC ball to prevent reverse flow in piping systems. The double union design allows the valve body to be removed from the pipeline without cutting pipe, making it easy to inspect or replace the ball. Suitable for chemical dosing lines, water treatment, and pump discharge applications.
