2603/2703/2604/2704 Series Manifold Valve

Brand: Noshok, Inc.
Features
  • 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 pressure rating at 200° F 
  • 2703/2704 series soft tip valves have 6,000 psi at 200° F 
  • Blow-out proof stem provides a secondary stem seal in the full open position 
  • 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) 
Options
  • Panel Mountings 
  • O-Ring Materials
