  • Combines isolating and venting in a single valve, eliminating the need for tubing and fittings
  • Block valve isolates the downstream process fluids, and the bleed valve exhausts upstream fluids enabling instruments to be removed without disturbing the permanent piping installation on the bottom
  • The 1/4" NPT vent plug is located 90º to the left and may be removed and replaced with exhaust piping to direct the fluids to a safe location
  • 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability
  • Blow-out proof stem provides a secondary stem seal in the full open position
