4-Way Direct Acting and Pilot Operated valves are used in applications for actuation of double acting cylinders and piloting of larger control valves. Pilot operated valves require the minimum operating pressure differential specified to ensure proper operation. Direct Acting valves do not have a minimum pressure differential requirement.

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 shown in the product specification charts. Use of non-lubricated gaseous media can affect valve life.

Coil Classification

Class F standard, Class H available
Class B standard on V9xx models

Agency Approvals

Standard valves with NEMA 4X or explosion proof solenoid enclosures are UL Listed and CSA Certified. (Consult Factory for Approvals on Models V933, V935 and V955). SIL-3 Capable (Models 73417xx, 74417xx, 73477xx). See certificate on page F20 in the Technical section of this catalog. For additional details, consult factory

Maximum Ambient Temperature

167°F

Minimum Ambient Temperature

-40°F for models 73417xx, 74417xx and 73477xx. Dew point must be more than 7°F below ambient.
