3.1 R 100 and R 101 Construction and function
R 100 and R 101 are gas pressure regulators.
Constant outlet pressure is ensured when the inlet
pressure or flow capacity vary.
The gas flows through the regulator housing in
arrow direction. The main diaphragm is actuated
via an impulse line from the outlet side by pressure.
The required outlet pressure is adjusted at
the spring.
The valve remains open as long as the outlet pressure
is below the set value. When reaching the set
point the regulator valve closes.
The measure work is directly mounted and operates
independant from the inlet pressure.
R 100 with double seat regulating valve.
Nominal diameters: DN 50, 80, 100, 150, 200.
R 101 with single seat valve
Nominal diameters: DN 25, 40, 50, 65, 100.
R 100-U Circulation regulators to limit pressure on
gas pressure discharge plants. Gas flows back to
the suction side of the compressor when the set
opening pressure is exceeded.
Nominal diameters: DN 50, 80, 100, 150, 200.

R 100-UD negative pressure regulators control the
gas throughput proportional to vacuum, f. e. of a
gas motor or negative pressure gas appliance.
