  • Compact design is ideal for installations with limited space, such as behind panels or in cabinets
  • Designed for use with differential pressure transmitters incorporating two isolation valves and an equalizing valve in differential pressure measurement
  • 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)
  • 3610 Series hard seat valves have 10,000 psi pressure rating @ 200 °F
  • 3710 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
  • 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
  • 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)

Please note that the standard o-ring in all the NOSHOK valves is FKM and the standard handles are 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 3710-FFC will be steel. When only the standard configuration is needed, no additional designations are necessary. Please consult the factory for special application requests.

To meet all of your specific application requirements, the following additional options are available for these manifold 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: 3610-FFC-P1)

NOTE 2: 
When a packing option is selected, an o-ring option is NOT available.

NOTE 3: The standard o-ring in all the NOSHOK manifold valves is FKM.

Dielectric Kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection. Dielectric Kits provide a non-conductive barrier between the process piping and the instrument and isolate components from the effects of electrical current. By eliminating metal-to-metal contact, current is halted to prevent corrosion and aid in the cathodic protection of the system.
