4111 & 4115 Slide Valve
Brand: Bifold - by RotorkSlide 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.
