12.4 RSD2 Restrictor Valve
12.4.2 Application / Function
• For the finer adjustment of the control behavior of the regulator
• For a outlet pressure control without fluctuations in the low load range
of the regulators
The RSD2 is a throttle valve which regulates the volume flow in the sensing/impulse line by means of a
continuously adjustable cross-sectional reduction. The setting is made tool-free by means of a rotary knob
and can be adjusted using a screw to be fixed. The throttle valve cannot be completely shut off, therefore a
guaranteed minimum flow is ensured.
12.4.1 Use
• For installation in the sensing/impulse line or breathing line of the control
device
12.4.3 Technical Data

galvanized / aluminum
• Temperature range, class 2 -30°C to +100°C
(operating/ambient temperature)
• Ex protection
The mechanical components of the device do not have any
potential ignition sources of their own and are thus not covered
by the scope of ATEX 95 (94/9/EC).
