Description
The gas pressure governors SERus and SERus-E are
spring-loaded proportional regulators with inlet pressu-
re compensation. On request they can be equipped with
a gas loss protection.
The axial design of the devices, which has been paten-
ted, provides high performance and regulation efficien-
cy coupled with extremely compact dimensions.
All gas pressure regulators are heat-resistant. In case of
fire a special heat-triggered valve closes the breather
vent.

Installation
Before assembling your SERus gas pressure regulator, re-
move the protective caps (if present).
The SERus regulator must be installed without pipe
braces. The arrow located on the SERus housing indi-
cates the flow direction. Use a spanner measuring 52
mm across the flats*) as a counterhold. The use of pipe
wrenches is not allowed.
After installing, assure that there are no leaks.
Install, inspect and monitor the regulator as outlined in
the national rules and regulations and in accordance
with the accident prevention regulations.

The SERus service governor is fitted with a safety di-
aphragm which prevents gas from blowing out of the
regulator in case that the multifunctional diaphragm is
damaged.
In the event of damage, the safety diaphragm does not
work as a working diaphragm.
A strainer situated inside the inlet orifice traps any large
particles of foreign material as the gas flows through the
governor.
For further information about the capacity and the spe-
cific features of this regulator, please refer to the relevant
brochure and to the identification plate.

Commissioning
(Inlet and outlet taps are closed)
Open the inlet tap slowly. The gas flows into the SERus
regulator and turns it to its closing pressure position.
After opening the outlet tap the regulated gas flow is
directed to the consumption unit.
If the SERus regulator is fitted with an integrated gas loss
protection, the gas will flow to the user only after the gas
loss protection has been opened.
This happens automatically if the outlet tap is closed and
gas pressure comes in (the inlet tap is open).
After approximately 20 to 100 seconds the gas loss pro-
tection opens thus bringing the SERus governor into
its closing pressure position. As a result, the outlet tap
opens.
The outlet pressure is preset at the factory and cannot
be changed.
