886 Series - Stainless Steel Swing Check Valves

A swing check valve is made up of three parts:

• Valve Body
• Bonnet
• Disc connected to a hinge

With increase in flow, the disc moves away from the valve body to allow forward flow of content. As the pressure of flow decreases, the disc begins to come back to the valve body, closing the flow and preventing backflow in turn.

The swing check valves are manufactured in various sizes and designs to allow for varied applications.  These valves open fully with high pressure and close down completely as flow dies out.

Evergreen Midwest provides swing check valves manufactured with stainless steel and soft seats. Use of stainless steel makes these valves easier to maintain.
