When you receive the shipment, inspect the container and equipment for signs of damage. Note any evidence of rough handling in transit. Immediately report any damage to the shipping agent.
General Description
The OMEGA®PV100 Series Electronically Controlled Proportional Valves are two-way normally closed valves. When the valve is deenergized, pressure is sealed off by the force of the plunger assembly return spring and the seal in the plunger assembly. When the valve is energized, the plunger assembly moves upward, permitting flow through the valve. The valve is direct acting. Higher current or control signal results in more plunger movement and more flow.
Installation
Port Identification
Apply inlet pressure to the port marked “P”.
Mounting Position and Pressure Limits
Valves can be mounted directly on piping and are designed to operate in any position. Two 8-32 tapped mounting holes 1⁄4” deep are provided in the base of the body. Line pressure must not exceed the nameplate rating.
Piping
Remove closures from ports and connect pressure lines to proper ports. All valves have 1⁄8" NPTF fittings. Tightening torque on the 1⁄8" NPT should not exceed 38 in-lbs.
Media Filtration
Filtration of air lines is recommended. Install the filter in the inlet side as close to the valve as possible. These valves have no sliding fits and are generally not sensitive to a small amount of foreign material, however, they do contain soft rubber inserts. Dirt or foreign material in the media may cause excessive leakage, excessive wear, or in exceptional cases, malfunction.
Electrical Connection
Electrical supply must conform to nameplate rating. Connect coil leads to DC voltage using standard electrical practice.

If the coil housing is located in an inconvenient position, the housing nut can be loosened and the housing rotated to any convenient position. Then re-tighten the nut to 13 to 35 in-lbs.
Coil Housing Temperature
Standard valves are supplied with coils designed for continuous duty service. Normal free space must be provided for proper ventilation. When coil is energized continuously for long periods of time, the coil housing will become hot 54 to 71°C (130 to 160°F). The coil is designed to operate continuously under these conditions. Any excessive heating will be indicated by smoking and/or odor of burning insulation.
Lubrication
Lubrication is not required.
Maintenance Instructions
Valves are calibrated at the factory and should not be disassembled by the user.
