The Circle Seal Controls model 9532B-1PP Shutoff Valve provides a precise, miniature, leak-proof valve for use in vacuum or pressure service for instrumentation, inert gas test stands, hydraulic clamps, jacks, etc.



  • Leak proof in vacuum or pressure service: o-ring on cylindrical face of plug prevents leakage past inlet port
  • No stem leakage: no stem packing adjustment required; plug seal o-rings absolutely prevent external leakage
  • Minimal pressure drop: straight-through flow passage
  • Positive position indication: position of handle instantly shows position of valve
  • Can be used for metering: by turning the handle between the full “on” and “off” positions, different amounts of flow will be achieved
  • Effortless opening and closing: quarter-turn full-open to full-close; no spring used; no adjustment necessary
  • Easy to maintain: o-ring seals virtually eliminate wear; simple repair without removing valve from the line by replacing three o-rings
  • Convenient “T” handle: 90-degree actuation; color-coded for various gases and liquid service
  • Bleed hole: an optional bleed hole in the plug vents fluid trapped downstream
