          NOSHOK 2170 Series 2-Valve Block & Bleed, Soft Seat Needle Valves


          • 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
          • 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
          • 6,000 psi pressure rating @ 200 °F
          • Replaceable Delrin® seat, and straight through porting for bidirectional,
            high capacity flow and easy roddable cleaning
          • PCTFE or PEEK soft seat optional
          • 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 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
