Connectors

 N/A NOSHOK offers Stabilized & Non-Stabilized Connectors, as well as Stabilized Connectors With Integral Block Valve designed to reinforce the entire installation by shifting radial-stress load away from the NPT connections.

Dielectric Kits DK Series

 N/A 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.
  • One Piece Dielectric Gasket, Pair, Steel, Acetal (DK1)
  • One Piece Dielectric Gasket, Pair with Stainless Steel Bolts, Stainless Steel, Acetal (DK1-SS)
  • PTFE Gasket with Dielectric Shim, Pair, Steel, PTFE, PVC (DK2)
DK1
  • Single piece design combining a Acetal sealing gasket and Acetal dielectric shim
  • Bolts, washers and dielectric bushings are included with the kits
  • Cannot be used in conjunction with seal rings or o-rings
  • Seal rings or o-rings not required
DK2
  • Used as an alternative to a one-piece design when a separate sealing gasket or o-ring is required
  • Two piece design consisting of a PTFE sealing gasket and PVC dielectric shim
  • Bolts, washers and dielectric bushings are included with the kits
Specifications:
  • Material: Acetal, PVC
  • Max operating temp 150 ºF
  • Dielectric strength exceeds 1/32 air arc gap approximately 2,500 Vdc
All 316SS products meet the requirements of NACE MR0175/ISO 15156-3.

Note

Note

 N/A 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.

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.
  • 1 If a packing option is chosen, maximum pressure rating is 6000 psi. Refer to the "Pressure vs Temperature: Packing Style with Compatible Fluid" chart.
