Pressure Tech MF Series – Medium Flow Regulators
Pressure Tech MF Series – Medium Flow Regulators
The MF Series includes piston-sensed and diaphragm-sensed medium-flow regulators for both gas and liquid applications. With models ranging from compact stainless-steel designs to regulators built for aggressive service and hydraulic applications, the MF Series delivers stable and accurate performance across a wide range of process conditions.
Why it matters
This family of regulators is designed to provide precise pressure control for analyser, instrument, and process applications. With options for ceramic seats, specialist materials, and reference tracking, the MF Series ensures reliable service in environments where stability, safety, and compliance are critical.
