  • 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
  • Block valve is located on the right and the bleed valve is located on top in a 90º orientation, venting is to the left

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.
