3/4″ Swing Check Valve — Brass

Swing Check Valve

• 3/4″ FIP
• Lead Free Brass
• Low Resistance to Flow
• Can be Installed either Horizontally or Vertically

Swing checks have a hinged door shaped like a disc that hangs inside of the valve. Pressure from the fluid entering the inlet pushes the door open, allowing flow through to the outlet. The door only opens one way, so fluid pushing from the outlet will not flow backwards through the valve. Swing checks tend to be less expensive, and impart low resistance to flow. They can be installed horizontally and vertically where the fluid flows from the bottom up, but cannot be used where flow travels in from the top to the bottom, as the disc will hang open if there is no flow. They may make noise when closing, due to the disc slamming shut when flow stops.
