PFR7

Line Pressure Regulator

The pressure regulator PFR7 is for the installation in line systems with large gas flows.

The line pressure regulator PFR7 is characterised by an accurate regulation and a large throughput.

The spring-loaded pressure regulator works according to the principle of the force equilibrium between the adjusted spring force and the outlet pressure.

It can be equipped optionally with an inlet and an outlet gauge.

The use of stainless steel in connection with elastomere made of viton permits the application of this pressure regulator with aggressive media.

Through the large effective diaphragm surface, at low pressure variant, optimal controllability is guaranteed. 

To identify the correct order code for your PFR7

Start with the model number, then add the appropriate number options from column A, B, C & D in the table below followed by the gas to be used.
