Size:1 1/2" Slip/Slip - V17221B ($15.99)2" Slip/Slip - V20221B ($17.99)   More info Hayward Ball Check Valve - Straight Hayward True Union Ball Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters, or process equipment. Operate without the need for any adjustments or settings. Line pressure moves the solid plastic ball off the elastomer seat, opening the valve. When the inlet flow stops, back pressure moves the ball back onto the seat stopping the flow. Additionally, this valve features a unique square-cut elastomer seat to seal at low back pressures. A true union design allows for easy removal from a piping system without breaking down piping connections. Because of their all-plastic construction, these valves will never jam or stick as a result of rust or corrosion. Also they will not contaminate sensitive fluids that come into contact with them.
