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.
FEATURES
-
Superior flow coefficient (Cv/Kv)
-
Stainless steel moving internals parts
-
Cast steel body
-
Low pressure drop across valve
-
Flanges and face-to-face dimensions to customer specification
