A pressure regulating valve is designed to maintain a desired downstream pressure irrespective of the flow requirement. The LFC™_3B variable ratio pressure regulating 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.



The LFC™_3B Pilot operated pressure regulating 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 assembly combined with a pilot are designed to use inline fluid pressure to create specific conditions in the system.

Its equipped with a 3-way pilot that controls the downstream pressure. A needle valve allows upstream pressure to flow into the valve top closing compartment at a controlled flow rate.

The pilot releases pressure from the valve to compartment at an adjustable rate. By adjusting the adjustment screw, the downstream control pressure can be adjusted to the desired downstream pressure. The pilot will ensure that the downstream pressure will remain stable, even if the upstream pressure changes with demand changes.
