          • 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 static pressure transmitters, switches
            or gauges to be removed without disturbing the permanent piping installation
          • Block valve is located on the right and the bleed valve is located on top in
            a 90° orientation, venting is to the left
          • 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance
            and reliability
          • Soft tip valves feature a patented Delrin® non-rotating soft tip stem,
            and a back-up metal-to-metal seal (U.S. Patent 6,820,857)
          • 2603/2604 Series hard seat valves have 10,000 psi pressure rating @ 200 °F
          • 2703/2704 Series soft tip valves have 6,000 psi 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 Grafoil® 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 caps for bonnets and stems (non-packing)
          • Patented body-to-bonnet, metal-to-metal seal is designed to significantly
            increase the pressure range of the valve (U.S. Patent 7,758,014)
