OMEGA®pressure volume
controllers provide an easy means of
rapidly and accurately adjusting the
pressure in a closed system to within
0.00025 psi. They can be used with
digital pressure gauges, dial gauges,
transducers, pressure switches, air
deadweight testers, manometers,
and similar devices. OMEGA
pneumatic controllers are available
for use with pressures up to
3000 psi.
Engineered to provide superior
performance and safety, these
devices incorporate a unique
pressure balance valve. This valve
is opened during initial system
pressurization. When opened, the
valve provides equal pressure to
both sides of the piston assembly
(see Figure 1). After the system
has been pressurized, the valve is
closed. Once the valve is closed,
a change in piston position will
change the pressure within the
system. Simply turning the large
pressure adjust knob repositions
the piston to increase or decrease
the pressure.
Equalization of pressure on both
sides of the piston ensures ease
of pressure setting. In addition, the
valve performs a safety function. The
balance valve will open automatically
if an excessive pressure differential
is generated across the piston. In
essence, the valve serves as a
safety relief valve and protects the
controller from damage due to
excessive pressure differentials
within the unit.
