- 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
- Valves are located on the top to fit into compact spaces and two holes are provided for mounting, 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 Acetal non-rotating soft tip stem, and a back-up metal-to-metal seal (U.S. Patent 6,820,857)
- 2602 Series hard seat valves have 10,000 psi pressure rating @ 200 °F
- 2702 Series soft tip valves have 6,000 psi pressure rating @ 200 °F
- 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 stems are 316 Stainless Steel
- Stem and bonnet 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)

† If a packing option is chosen, maximum pressure rating is 6,000 psi. Refer to the "Pressure vs Temperature: Packing Style with Compatible Fluid" chart.
* Other o-ring materials available on request.
** Hard seat only.
*** Soft tip only.
Please note that the standard o-ring in all the NOSHOK valves is FKM and the standard handles are isolation 1-3/8" mini “T” handles (HL7) and equalizing 1-3/8" mini “T” handles (HL7).
The handle material will always match the material of the valve, unless otherwise specified. For example, the 1-3/8" mini “T” handle (HL7) on the 2602-FFC will be steel. When only the standard configuration is needed, no additional designations are necessary. Please consult the factory for special application requests.
