2603/2703 & 2604/2704 Series 2-Valve Block & Bleed Manifold Valves
Hard Seat & Soft Tip (0.156" Orifice)


  • 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)
