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.
PFR7-1-2-1-1-Argon specifies a PFR7 model in brass with viton diaphragm, no gauges & 0.1-2.5 bar pressure area, for use with Argon gas.
