Oil & Gas
  • 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 90° 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
  • 10,000 psi hard seat pressure rating @ 200 °F
  • Blow-out proof stem provides a secondary stem seal in the full open position
  • FKM o-ring seal and PTFE back-up ring below the stem threads to protect from corrosion and galling; PTFE or Graphite packing optional
  • All stems are 316 Stainless Steel
  • All stem threads are rolled for strength and ease of operation
  • One-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads
  • Slotted spring pin to prevent accidental loosening
  • Vinyl dust cap for bonnet and stem (non-packing)
