Oxford Flow - IM-F+ Series - Gas Regulator

High performance gas pressure regulator

Flanged construction for DN50-DN150 (2"-6") pipework


The IM-F+ Series pilot-controlled regulator range offers high levels of performance for Natural Gas and other process gasses.

The patented technology from Oxford Flow's IM Series PRV is now available with integral flanges for use in the most demanding applications.

The robust stainless steel design has been engineered to deliver the same high levels of accuracy and responsiveness in an industry standard form factor for simple integration into existing pipework.
