The ROSS^® ANSI valves W70 Series are base mounted spool and sleeve 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 spool and sleeve design means there are no seals to wear out.

• Pilot operation provides high shifting force with low power consumption
• Suitable for vacuum service with or without external pilot supply
• Manual override: Flush, rubber, non-locking
• Individual sub-base or manifold base mounting
