The ROSS^® ANSI Valves W74 Series are base mounted poppet valves that conform to the American National Standards Institute (ANSI) standards for valve-to-base interface configurations, including plug-and-socket electrical connections between valve and base.

These ANSI Size 1, 2.5, 4, 10, and 20 valves are available as, 2- and 3-position, 5-ported 4-way solenoid pilot or pressure controlled valves with either internal or external pilot supply. The poppet design is highly tolerant of contaminated air and are self compensating for wear.

• Pilot operation provides high shifting force with low power consumption
• Non-locking manual override
• Individual sub-base or manifold base mounting
• Suitable for vacuum service (with external pilot supply)
