Catalog literature: Shutoff Valves Catalog.pdf Acrobat DC

The Circle Seal Controls model 933T-2PP Shutoff Valve is a Globe design that can be used at pressures between 0-6000 PSIG. It is constructed in 303SS with Neoprene seals and has 1/4″ FNPT connections.



  • Positive leak-proof shutoff: the unique Circle Seal design engages a precision-machined stem into a resilient o-ring for bubble-tight sealing of liquids and gases
  • Full flow passages: resistance to fluid flow is minimized by flow passage design enabling pressure drop compatible with high pressure shutoff valve performance
  • Protected o-ring: spring-loaded sleeve follows stem as stem is withdrawn; sleeve encloses o-ring and protects it against extrusion and cutting action of fluid flow
  • Freedom from wire drawing: valve design and dead-tight shutoff prevent wire drawing, permitting exceptionally long maintenance-free service life
  • Panel mount standard
  • “A”, “B”, and “N” series: provide full flow in either direction, accurate metering capabilities, and zero shutoff
  • “T900” series: provide a quick snap to open or close dead tight; positive locking cam to hold valve open or closed
  • “900” series: an easy turn to open or close dead tight; flow is only under the seat
