4111 & 4115 Slide Valve

Slide valves Type 4111 (normally closed) and 4115 (normally open) are pilot-operated, three port, two position valves with a spring-return action. A major feature of the valve design is elimination of the continuous leakage which is characteristic of conventional lapped-face spool valves. The valve incorporates special high pressure seals which prevent leakage and so render the valves suitable for use with many fluid media.
