2 Orion/MPV-10K Adjustment & Maintenance Manual
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.

NOTE: A small coating of Fluorinated Krytox grease (PN 55593) should be applied to both sides of O-ring prior to
installation.
2.2 Recommended O-ring materials
NOTE: Ratings are recommended for use in the Condec products and are meant to be used only as a guide. Based on
your application you may need to do testing. The O-ring material applications listed below are for reference only and are
not to be used in the valves.
Nitrile Buna - N (BN)
The standard for most general applications (petroleum-based lubricants, hydraulic oils, gasoline, fuels, alcohol,
LP gases, water, and many other media).
Temperature range: -65 to +300 F
Pressure rating: 0-6000 PSI
Neoprene (C)
For refigeration (freon gases, carbon dioxide gases, chlorine, ozone, sunlight exposure. FDA approved for food
and beverage, odorless, tasteless, non toxic).
Temperature range: -80 to +260 F
Pressure rating: 0-6000 PSI
Ethylene-Propylene (EP)
For hot water, steam, acids, alcohols, alkalis, keytones, phosphate, and brake fluids.
Temperature range: -67 to +302 F
Pressure rating: 0-6000 PSI
Fluorcabon "Viton" (V)
High temperature compatible with wide range of fluids and chemicals. Acids, oils, fuels, solvents and gases.
Temperature range: -65 to +500 F
Pressure rating: 0-10000 PSI
