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.
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
FLOW COEFFICIENTS & FLOW RATES
160 bar (max) working pressure
Up to 85ºC with standard seals.
Liquid and gas with low content of suspended solids.
2” (50 NB) to 24” (600 NB)
SABS 1123, BS4504, BS10, ASME B16.34, ANSI B16.5
pH levels & chlorides
Parts of the valve are made from stainless steel and can withstand a low level of chlorides.
The valve can be installed in any position
Seat Leakage - B16.104 class III, IV, V or VI, depends on valve type and application.
