NON-SLAM CHECK VALVE

The Hydrocore™ non-slam check valve prevents back flow while minimizing the water hammer effect during the valve’s closure.

Principle of Operation 

  • The Hydrocore™ non-slam check valve
    gradually opens when the pump starts running.

  • Gradually closes at a speed controlled by the valve’s speed control orifice.

  • Gradually reduces the flow through the valve while closing.

  • Utilizes a spring to ensure a valve closed position. 

  • Can be installed in a horizontal or vertical position.

 

Long life & Low Maintenance

All moving parts and surfaces of the Hydrocore™ non-slam check valve are made from stainless steel in order to minimize corrosion and prevent scale buildup. The valve’s shuttle is suspended by bronze bushes.
