The FR 1 is a single-stage precision pressure regulator with balanced main valve.
The FR 1 is for installation in piping systems, for installation in control panels or for inte- grating in instruments (instrumentation).
The Integrated balanced poppet ensures that even when inlet pressure drops down a con- stant operating pressure is guaranteed (dual stage effect).
An easily replaceable sinter metal filter ele- ment is integrated into the pressure regulator as standard.
The precision pressure regulator FR1 is used particularly in the following areas:
• - Process engineering
• - mbar applications
