  • 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 90º to the left and may be removed and replaced with exhaust piping to direct the fluids to a safe location

Assembly Options N/A NOSHOK offers multiple assembly options to meet your specific system requirements. Consult factory to discuss your customized solution.
Note N/A 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.

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.
