20702070 SERIES
- Combines isolating and venting in a single valve, eliminating the need for tubing and fi ttings
- Block valve isolates the downstream process fl uids, and the bleed valve exhausts upstream fl uids 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 fl uids to a safe location
- 100% helium leak tested to 1 x 10 -4 ml/s for performance and reliability
- 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 Graphite packing optional
- 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 cap for bonnet and stem (non-packing) Block & Bleed, Hard Seat Needle Valves, 2-Valve NOTE: All NOSHOK valve products conform to the MSS SP-99 instrument valves standards, and valves supplied with packing also conform to MSS SP-132 compression packing systems for instrument valves standard.

2 0 7 0 – FFC EXAMPLE To meet all of your specifi c application requirements, the following additional options are available for these needle valves. To order all or any of these options, simply add them to the part number as shown in the diagram below. NOTE 1: The example shown includes ALL possible additional options. Please include ONLY the options required for your application when building your part number. (EXAMPLE: 2070-FFC-HL5) NOTE 2: When a packing option is selected, an o-ring option is NOT available. * Other o-ring materials available on request. Please note that the standard o-ring in all the NOSHOK valves is FKM and the standard handles are block “T” handles (HL2) and bleed mini “T” handles (HL1). The handle material will always match the material of the valve, unless otherwise specifi ed. For example, the “T” handle (HL2) on the 2070-FFC will be Steel. When only the standard confi guration is needed, no additional designations are necessary. Please consult the factory for special application requests. 2 0 7 0 – FFC – P1 – T1 – HL3 EXAMPLE with Additional Options † If a packing option is chosen, maximum pressure rating is 6,000 psi.
