Ball Check Valves

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.  Valve sizes 1/2" to 6" feature a true union design. This allows for easy removal from a piping system without breaking down piping connections.

Swing Check Valve

A swing check valve utilizes a swinging disc, which requires only minimal back pressure to close the valve. This valve can also be modified, with a lever and weight or spring, to assist in seating faster to eliminate shock.

Wye Check Valve

Y-Check Valves prevent reversal of flow in piping systems. They are ideal where backflow could potentially cause damage to pumps, filters or process equipment. The valve operates without the need for any adjustments or settings. A plastic coil (not a spring) supports the disc inside the valve body. When the inlet flow stops, backpressure (a minimum of 2 PSI is required) moves the disc with its elastomer o-ring onto a plastic seat, shutting off the flow.
 

Wafer Check

Wafer Check Valves operate without the need for any adjustments or settings. The valves plastic disc, with replaceable O-ring seals, is designed to provide a bubble-tight flow shutoff. When inlet flow stops, back pressure* moves the disc with its O-ring seal into the valves plastic body-shutting-off the flow.
