pressure regulator principle
Qmt-tech's
line
pressure regulator
(pressure stabilizing unit)
is intended to regulate the pressure of
medical gases from
nominal supply system pressure to nominal distribution pressure.
According to the
principle of
single fault condition
*, the unit contains two mutually independent operating circuits. One is
intended for normal operation and the other as a reserve during, for example, service and inspection.
This means that it is possible to replace regulators and safety valves during operation.
Pressure
transducer for outlet (nominal distribution) pressure is standard. Pressure transducer for inlet (nominal
supply system) pressure is option. Optionally contact gauges can be fitted instead of pressure
transducers.
The unit is equipped with safety relief valves on the outlet pressure side for each circuit.
These are equipped with a common
relief gas
pipe. The gas outlets are used as a measuring point.
*
Single fault condition:
Situation in which a single component, which is to protect against a safety risk
in an
equipment, is defective, or when a single external, abnormal circumstance is present.
