General Description:
3 and 4 Way Low Power, Direct Acting and Pilot Operated Valves in Brass, Aluminum and Stainless Steel are suitable for use in general industrial process fluid control applications and for control valve pilot actuation where power consumption is a concern.

These valves are also compatible for use in factories utilizing Distributed Control Systems (DCS) with power limitations integral to their bus networks and back up power systems as well as in Safety Instrumented Systems (SIS).

Low Power operator designs consider system parameters for supervisory or leakage currents.

Pilot operated valves require the minimum operating pressure differential specified to ensure proper operation. Direct acting valves do not require a pressure differential.

Installation
Valves can be mounted in any position.
The preferred orientation is with the coil vertical and upright
Compatible Fluids Lubricated Air and Inert Gases
Use of non‐lubricated gaseous media will substantially limit valve life.
