INTRODUCTION
1.1 SCOPE
This manual provides general information for the installation, operation
and service of CONCOA Gas Pressure Regulators.
1.2 USE
The regulators are designed to control and reduce high gas pressure
from a cylinder or pipeline, in one or two stages, to the working
pressure required for the equipment using it.
According to design and requirements of individual regulators, the
following may be provided:
a. A screw, knob or similar device to adjust pressure manually and (as
in the vacuum regulator) by remote control; or to change factory
pre-set pressure (as in the pipeline regulator).
b. One or two stages of valves, seats, diaphragms, and auxilliary
parts..
c. Various types of inlet and outlet connections.
d. Built-in inlet fi lters, to prevent entry of solid foreign matter.
e. Gauges, to indicate inlet and outlet pressures.
f.
A built-in relief valve to protect the regulator.
g. A fl owmeter to measure gas fl ow.
h. A fl ow adapter on fi xed pressure regulator (See Table and Figure 1).
