Description
The Model 42 Precision Pressure Regulators control air pressures in applications
where precise and dependable regulation is required, such as pneumatic
instrument circuits, test stands, production checking fixtures, and industrial
air gages. As such, they are suitable for deadend service, and flows up
to a maximum of 110 scfm.
A unique, two-stage piloted design provides outstanding
accuracy. Rugged construction—with no links, levers, pivots, or other
friction-producing members—ensures reliable, maintenance-free operation.
These features allow
a regulator to maintain constant output pressure, regardless of even the
widest changes in flow or supply pressures. In fact, a regulator using a
Model 42 is practically a self-contained pressure controller operating its
supplyplunger
valve via a built-in, high-gain pneumatic amplifier.
A fine-turn, precision screw is used to manually load the
range spring, which sets the regulated pressure. When the adjusting knob
is turned clockwise, the increased spring force is exerted on the top diaphragm
assembly, decreasing the nozzle clearance and increasing the pilot pressure.
Because the source for pilot pressure is supply air flowing to the pilot
pressure chamber through the restriction screw, the increased pilot pressure
forces the exhaust diaphragm assembly downward. This action closes the exhaust
port, and contacts and moves the valve plunger, which opens the supply port.
This increases the regulated output, which also feeds back to the top diaphragm
assembly. The regulator locks-up or throttles at the new output value when
the feedback force of the top diaphragm assembly equals the range spring
force.
A safety release valve is incorporated in the top diaphragm assembly of several models. It operates if the regulated pressure increases 3 tnÚ psig more than the set pressure and exhausts air through the atmospheric vent in the top housing. Overpressure causes the diaphragm to move upward, which opens the safety release valve.
