LINE-FLUID ACTUATED VALVE
The Hydrocore Line-Fluid Actuated valve is used for remote isolating of pipeline applications by using the line-fluid pressure. Is mainly used in: Industrial Water Systems, Municipal Water Supply Systems, Pump Stations, Mine Water Reticulation and Petrochemical Plants.
Benefits of the Hydrocore Line-Fluid Actuated Valve
No electric actuators that are expensive and that have limit switches that are seldom set correctly causing the valve to fail.
No gears, spindle, bushes, shafts, keys and keyways that can wear out and cause the limit switch to go out or cause the actuator to fail.
The valve has a superior Cv compared to other globe valves.
No pneumatic systems.
The needle valve can be set very accurately so that the valve closes at an appropriate speed so as to prevent the occurrence of water hammer.
The valve always has positive pressure (full column pressure) on top of the shuttle when the valve is in a closed position. This prevents valve seat leakage and seat damage. When the valve is in an open position, it prevents the valve from being in a partly open position. This ensures that there is no reduced pressure drop over the valve causing undesired energy and financial losses.
Does not need an expensive actuator to operate
Does not need a gears, spindle, bushes, shafts, keys and keyways that can wear out and cause the limit switch to go out or cause the actuator to fail.
No pneumatic systems.
Superior flow coefficient (Cv/Kv)
Can be maintained in line
High cavitation resistance due to design

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.
