21702170 SERIES
- 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 performance and reliability
- Replaceable Acetal 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 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, Soft 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 1 7 0 – FFC EXAMPLE To meet all of your specific 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: 2170-FFC-PK1) 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 1-3/8" mini “T” handle (HL7). The handle material will always match the material of the valve, unless otherwise specified. For example, the “T” handle (HL2) on the 2170-FFC will be Steel. When only the standard configuration is needed, no additional designations are necessary. Please consult the factory for special application requests. 2 1 7 0 – FFC – PK1 – P1 – T1 EXAMPLE with Additional Options ORDERING INFORMATION21702170 SERIES
