Ball valves are commonly employed for flow control and water supply shut-off purposes. They enable the removal of pond equipment for maintenance without necessitating the drainage of the entire system. For instance, it is imperative for all pumps to be equipped with slide valves or ball valves on both the inlet and outlet. These ball valves are crafted from Industrial grade PVC and exhibit a double union design. They possess collars at each end, facilitating the disconnection of the ball valve from the pipe at both ends without the need for cutting.
