3-Way Pilot Operated valves are used in general industrial applications and control valve pilot actuation where higher pressures and flows are required. Pilot operated valves require the minimum operating pressure differential specified to ensure proper operation.

Installation

Valves can be mounted in any position. The preferred orientation is with the coil vertical and upright.

Compatible Fluids

Lubricated Air, Inert Gases, Water, Light Oil (300 SSU) and additional fluids compatible with materials of construction, as listed in the product specifications charts. Use of non-lubricated gaseous media can affect valve life.

Coil Classification

Class F Standard – Class H Available

Agency Approvals

Standard valves with NEMA 4X or explosion proof solenoid enclosures are UL Listed and CSA Certified.
