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.

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.
