Storm Water and Wastewater Applications. Our plastic ball check valves employ a free moving ball, which unseats to permit flow in one direction, but seals against a seat to prevent backflow. 
A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows. A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball.
They are delivered with NBR lined ball as standard and optionally with ball of. 
Low sealing torques; Easy maintenance; Resilient metal seat options; Optional stainless steel version. Sinking ball check valve to prevent reverse flow, suitable for water and wastewater applications. The ball check valve is a valve mainly designed for viscous solids-laden media and sewage.
Ball check valves can work on horizontal or vertical ascending. Heavy duty cast iron or plastic construction. Check valves for waste water and raw water service.
The Hydrotite Ball Check Valve is suited for sewer applications and features a self cleaning ball with silent operation. The ARVis a ball check valve, under normal flow the valves solid PTFE ball is pushed away from it’s seat and fluid flows through the valve, in a backwards flow. Reflux prevention based on the ball check principle in which in the open. For installation information, see IOM manual.
Nil-Cor check valves have been designed to achieve strengths equivalent to metals with the inherent corrosion resistance of advanced polymer matrix.
