LFC™_1B Water Hydraulic Actuated Valves

LFC 1B Water Hydraulic Actuated Isolation ValvesOVERVIEW

The LFC™_1B Water hydraulic actuated isolation valves is based on the same design as the LFC™_1B pressure regulating valve. Water hydraulic actuated valves are more cost effective than the LFC™_1B electrical actuated valves. The upstream water hydraulic power are used to actuate the LFC™_1B isolation valve. The speed of the valve can be adjusted to any desired speed fairly quickly and easily.

The LFC™_1B Water hydraulic actuated isolation valve are generally used for remote isolation, dissipator isolation/ level control valves. Using line fluids removes the need for any gearboxes or handwheels which makes them ideal for applications where tampering is a problem.

LOW OPERATING TORQUE

The LFC™_1B Water hydraulic isolation valves are hydrostatically un-balanced to enable easy opening and closing at any pressure and differential conditions. It does not require the use of a gearbox or a by-pass valve to balance pressure between the inlet and outlet. 

OPERATING CONDITIONS

These valves are designed to operate in systems with relatively clean media like water or other liquids with a low percentage of suspended solids and chlorides. The valve's operating pH range is 2 - 14 pH.

SIMPLICITY

The LFC™_1B Water hydraulic valve is designed to minimize wearing parts and in effect only has one moving part called the plug assembly. The plug assembly is a piston that is engineered to be un-balanced. The un-balanced plug uses the inline fluid pressure to remove the influence of differential pressure on operating torque. As such, the valve operating torque is the torque required to overcome the sum of the friction forces generated between the valve body, seals and the cylinder plus the weight of the plug (depending on the installation con figuration). This torque requirement is not affected by inline pressure variants and therefore makes these valves extremely good for actuation applications as well as for isolation valves where manual operation is required. Removal of gearboxes reduces maintenance requirements and improves troubleshooting times. The water hydraulic actuators/ control panels are simple in comparison with an electrical actuator. The LFC™_1B Water hydraulic valve can easily be fitted with limit switches to give open and closed indication.

LOW MAINTENANCE REQUIREMENT

All the moving parts of the LFC™_1B water hydraulic actuated isolation valves are manufactured from stainless steel which increases reliability and durability. The LFC™_1B requires minimal maintenance, the majority of which, can be conducted with the valve remaining in situ.
