HYDROMINE™ LFC_3B Water Hydraulic Actuated Valves
OVERVIEW
The HYDROMINE™ LFC_3B Water hydraulic actuated isolation valves is based on the same design as the HYDROMINE™ LFC_3B pressure regulating valve. Water hydraulic actuated valves are more cost effective than the HYDROMINE™ LFC_3B electrical actuated valves. The upstream water hydraulic power is used to actuate the HYDROMINE™ LFC_3B isolation valve. The speed of the valve can be adjusted to any desired speed fairly quickly and easily. The HYDROMINE™ LFC_3B Water hydraulic actuated isolation valve are generally used for remote isolation, level control or pump discharge control valves. Using line fluids removes the need for any gearboxes, electrical actuators or handwheels which makes them ideal for applications where tampering is a problem.
The HYDROMINE™ LFC_3B water hydraulic actuated valve has been developed to present a robust, simple and cost-effective low pressure (up to 2.5 MPa / 363 psi) solution to fluid handling issues in any industrial sector.
SIMPLICITY
The HYDROMINE™ LFC_3B 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 unbalanced. The unbalanced 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 configuration). 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 valve uses a water hydraulic control panels or solenoid valve to operate, and it are simple in comparison with an electrical actuator. The HYDROMINE™ LFC_3B Water hydraulic valve can easily be fitted with limit switches to give open and closed indication.
LOW OPERATING TORQUE
The HYDROMINE™ LFC_3B 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.
LOW MAINTENANCE REQUIREMENT
All the moving parts of HYDROMINE™ LFC_3B water hydraulic actuated valve are manufactured from stainless steel which increases reliability and durability. The HYDROMINE™ LFC_3B requires minimal maintenance, the majority of which, can be conducted with the valve remaining in situ.
