2602/2702 Series Manifold Valve

Brand: Noshok, Inc

Specifications
  • 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
  • Valves are located on the top to fit into compact spaces and two holes are provided for mounting, 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)
  • 2602 series hard seat valves have 10,000 psi pressure rating at 200° F
  • 2702 series soft tip valves have 6,000 psi pressure rating at 200° F
  • Blow-out proof stem provides a secondary stem seal in the full open position
  • All stems are 316 stainless steel
  • Stem and bonnet 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)
