Two-valve single outlet gauge valves that combine isolating, calibrating and venting facilities in a single compact unit

These valves enable gauges, pressure transmitters or switches to be installed and serviced reliably by reducing potential leak points. A threaded and plugged vent port enables safe installation of exhaust piping/tubing on hazardous service.

  • Compact design minimizes space requirements; low weight improves connection strength and reduces gauge whip.
  • Minimal instrument installation components reduce costs and decrease possible leak points.
  • Easy instrument check calibration using ¼" FNPT vent/test port.
  • Ball end stem eliminates seat galling, provides bubble-tight shutoff and long life. Hardened, non-rotating ball ensures perfect alignment closure.
  • Packing below threads prevents lubricant washout, thread corrosion, process contamination and eliminates galling.
  • Easily adjustable packing decreases replacement downtime and increases valve life.
  • Safety back seating prevents stem blowout or accidental removal and provides a metal-to-metal secondary stem seal while in the fully open position.
  • Dust cover prevents lubricant washout and protects bonnet assembly from contaminants.
  • ENC plated 316 SS prevents galling or freezing of stem threads.
  • Rolled stem, bonnet and male NPT threads provide additional strength.
  • Mirror stem finish in the packing area enables smooth operation and extends packing life.
  • Metal-to-metal body-to-bonnet seal in constant compression prevents bonnet thread corrosion, eliminates possible tensile breakage and gives a reliable seal point.
