Introduction

About This Manual

The ORION/MPV-10K is a pneumatic pressure

controller with precision vernier. A rugged, compact

controller manufactured by Condec, designed to

provide ease of operation and installation, by a

qualiﬁed technician.

Equipped to perform and be maintained on-site, these

controllers have proven to substantially reduce the

cost, system down-time and man-hours of labor

normally associated with these routine service

functions.

The patented controller was designed as an all

mechanical device that has been factory adjusted and

ready for on-site installation.

This manual has been written to give the user a simple

and clear explanation of how to operate, and

troubleshoot these controllers.

Before attempting to use either style,

Pressure Controller, the following

instructions must be carefully read

and understood by personnel utilizing

the equipment. This is a high-pressure

system. It is strongly recommended

that only personnel formally trained in

the use of pneumatic pressure

equipment be permitted to operate it.

Potentially dangerous conditions

could be produced through negligent

handling or operation of the valve due

to the high pressure used within the

unit.

These units are strictly for use with pneumatic pressures.

Erroneous readings and potential damage could result

from the introduction of hydraulic ﬂuids into the internal

valve body.

Authorized distributors and their

employees can view or download this

manual from the Condec distributor

1.0 Introduction

The ORION/MPV-10K represents the latest in technology, offering a combination of features, performance,

versatility and reliability not previously available in a pneumatic pressure controller. Some of the more

outstanding features are listed below:

•Simple Operation: Accompanying operator's manual provides clear, concise instructions for system

operation.

•ORION-2C, ORION-2D, ORION-3A: To obtain a speciﬁc pressure, either the Inlet Pressure valve or the

Vent (outlet) valve (two outer valves) may be used since both provide precise control. As the pressure

approaches the desired value, the valve being used for control should be slowly rotated clockwise to its

closed position. With a little experience, pressure values very close to the desired ﬁnal value may be

quickly achieved. To obtain exact ﬁnal pressure, slowly rotate the Vernier Control (middle) Knob in the

desired direction, clockwise to increase pressure.

•MPV-10K: 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. The valve has a ﬁne adjustment sensitivity. Very low torque is required to turn the vernier, so use

ﬁngertip adjustment.

•Safe, Clean Operation: All pressure components are made of brass, aluminum or stainless steel and

proof-tested to at least 150% of maximum operating pressure.

The heart of the ORION controllers are the two micro-metering valves and the vernier provided for control of

pressure. Overpressure protection must be customer provided, if required, by a fully adjustable pressure regulator

which is manually set to limit the system input pressure. The ORION/MPV-10K is designed for compatibility

with Nitrogen and shop air. Other O-ring materials are available through special ordering or repair kits.

2.0 Maintenance

This section outlines the mechanical repair procedures for the ORION/MPV-10K pressure source. The repair

procedures cover the major components and subassemblies which are critical to the proper functioning of the

calibrators and that will likely need periodic maintenance over the life of the unit. Only those persons who are

formally trained as skilled technicians should attempt to repair these units. All relevant safety precautions should

be observed due to the presence of high-pressure cylinders.

O-ring (valve is now in closed position).

6. Rotate gear(s) (small gears with 18 teeth) on isolation valve(s), counter clockwise (gear[s] will rotate

towards valve body) until they stop. Then rotate each gear clockwise 1/2 turn to open isolation valves.

7. Turn the supply pressure regulator to increase the supply pressure to between 80% and 100% of

customers line pressure (ORION-2C or ORION-3A: maximum 3000 PSI; ORION-2D: maximum 300

PSI).

8. Open the

VENT

valve to atmosphere to release line pressure, then close the

VENT

valve.

9. Slowly open the input valve by turning the knob insert (4) counter-clockwise until you notice the input

pressure gauge pressure increase. Then turn the knob insert (4) slightly clockwise until the pressure stops

rising.

10. Mark a radial line at the 12 o’clock position on the knob insert.

11. Turn the knob insert (4) clockwise to move the mark to the 6 o’clock position.

12. Turn the locknut (2) counter-clockwise until it contacts the bottom of the stop washer. Tighten the set

screw (34) on the locknut with the .050" hex wrench.

13. Install the input valve knob (3) on the knob insert (4) and engage its gear (5) with the smaller isolation

valve gear (6). Turn the knob clockwise until the isolation valve is slightly snug.

CAUTION:

do not use excessive torqure when doing this. The seat may be damaged

14. Remove the input valve knob (3). Align the set screws (25) with the indentations on the knob insert.

Install the knob on the knob insert (4) while engaging the knob gear (5) with the isolation valve gear (6).

15. Tighten the set screws (25) with the .061" hex wrench. The input valve is now adjusted.

16. To adjust the

VENT

valve (ouput). Close the input valve by turning the output valve knob clockwise.

17. Close the

VENT

valve knob insert (4) clockwise until slightly snug.

18. With the supply pressure at customer’s 100% line pressure (ORION-2C or ORION-3A: maximum 3000

PSI; ORION-2D: maximum 300 PSI). Open the

COARSE

valve until the indicated pressure stabilizes

and then close the

COARSE

valve.

19. Slowly turn the

VENT

valve (ouput) knob insert (4) counter-clockwise until you hear ﬂow from the

VENT

valve, then turn the knob insert (4) slightly clockwise until the pressure stops decreasing.

20. Repeat steps 10 - 15 for the

VENT

valve, replacing the term "input valve" with "output valve."

2.10 MPV-10K Manifold - Valve Adjustment Procedure (Customer Installation)

(MPV-10K - Refer to the List of Parts - Table 2-4 on page 19, and Figure 2-12 on page 21)

NOTE:

Customer must supply, as a minimum, input supply pressure with a supply guage and pressure regulator.

Tools required: hex wrench (.050")

hex wrench (.061")

1. Turn the supply pressure regulator off.

2. If not already done, remove the MPV-10K knob (15) using the .061" hex wrench.

3. Using a .050" hex wrench, loosen the set screw (13) on the MPV-10K valve locknut (12) and turn

locknut clockwise until it stops.

4. Align the set screws (16) with the indentations on the valve needle (3 or 6). Install the knob using the

.061" hex wrench.

5. Turn the supply pressure regulator, to increase the supply pressure to between 80% and 100% of

customer’s line pressure (maximum 10,000 PSI). Let system settle for 5 minutes.

NOTE:Some valves may not be recommended for 10000 PSI, because of O-ring material selection. See Section 2.2 on

page 2.

6. Slowly open the MPV-10K valve by turning the knob (15) counter-clockwise until you notice the

pressure of the input pressure guage increase. Then turn the knob slightly clockwise until the pressure

stops rising.
