Slide valves Type 3160/3163 (normally closed) and 3165/3167 (normally open) are manifold mounted, pilot-operated, three port, two position valves with a spring-return action.
A major feature of the valve design is elimination of the continuous internal leakage which is characteristic of conventional lapped-face spool valves.
The valves each incorporate special high pressure seals which prevent leakage and so render the valves suitable for use with many fluid media.
