Stainless Steel Swing Check Valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position.
Series - 150 To 600
Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.
Design Features
- Horizontal or vertical pipe can be used, easy installation
- Smooth flow channel, fluid resistance is small
- Disc closes quickly with low water hammer pressure
- Long service life and high reliability
- Sensitive action, good sealing performance
