Orion-3A Pneumatic Pressure Controller
Part #55287, Patent No. 4.698.998
SPECIAL FEATURES:
• Orion 3A is a variable volume pressure controller with on operating pressure from vacuum to
10,000 psi. It consists of two low torque, fine micro-metering valves with positive shut-off,
adjustable stop and soft seat. The pressure valve controls the inlet pressure and the other
valve vents to atmosphere.
• The vernier is located at the center of the controller and allows the operator a very fine
pressure adjustment (approx.
±
5% point max.) without using the pressure or vent valve.
• Selecting the appropriate O-ring material may extend the wide range of gas applications.
• There is one inlet, one outlet, and two test ports. One test port may be used to connect a
pressure transducer or pressure gage standard; the other test port may be used to connect
the unit under test.
OPERATION:
The pressure valve will begin to open when it is turned counter clockwise approximately 15
degrees. Full open position of the valves is achieved with a maximum of 3 1/2 turns from the
closed position. Use the pressure/vent valves to achieve
±
95% of the target pressure. The
pressure and vent valves must be closed before operating the vernier. The vernier is a piston
and cylinder configuration, which generates
±
5% pressure, or vacuum of the indicated
pressure. The vernier has a fine adjustment sensitivity of .005 psi. Very low torque is required
to turn the vernier... FINGERTIP ADJUSTMENT EVEN AT 10,000 psi!!!!!
