Brand: Bifold - by Rotork
Slide valves Type 3111 (normally closed) and 3115 (normally open) are pilot-operated, three port, two position valves with a spring-return action. 

Manifold mounted versions are also available. 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.
