HYDROMINE™ LFC_3B Manual Isolation Valve
OVERVIEW
The HYDROMINE™ LFC_3B Manual Isolating valves were designed to be simple and easy to operate. The HYDROMINE™ LFC_3B Manual isolation 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.
LOW MAINTENANCE REQUIREMENT
All the moving parts of the HYDROMINE™ LFC_3B Manual isolation valves 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.
LOW OPERATING TORQUE
The HYDROMINE™ LFC_3B Manual isolation valve is hydrostatically 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. The differential pressures do not affect the operating torque which results in a relatively flat torque curve allowing for the fitment of smaller actuators.
MATERIALS OF CONSTRUCTION & DIMENSIONS
All face to face dimensions are in accordance with ANSI B16.10 Class 150.
SIMPLICITY
The HYDROMINE™ LFC_3B Manual isolation valve is designed to minimize wearing parts and in effect only has one moving part called the plug. The plug is a piston that is engineered to be balanced. The 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 seals and the sleeve plus the weight of the plug (depending on the installation con figuration). This torque requirement is not affected by inline pressure variants and as such makes the balanced valves extremely good for actuation applications. Removal of gearboxes reduces maintenance requirements and improves troubleshooting times.
ROBUST, RELIABLE & EFFICIENT
Due to the minimal number of moving parts to affect the fluid control, the number of potential failures are minimized.
