4111 & 4115 Slide Valve

Brand: Bifold - by Rotork
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.
Features
  • Working Pressure: 690 bar (10,000 psi) maximum
  • Pilot Pressure: 4.5 to 17.2 bar (65 to 250 psi)
  • Operating Media
    • Main Slide: Mineral oils, water, water-glycol mixtures, crude oil and a variety of chemicals
    • Pilot Section: Air, H2S, bottled gases or any of the main slide media
  • Leakage: None
  • Recommended Filtration: 25 micron
  • Connections
    • 3/8" NPTF
    • Pilot: 1/4" NPTF
  • Flow Rate, Nominal: 54 litres/min (12 imp galls/min)
  • Working Temperature - Standard: –20° to 130°C (-4° to 266°F)
