NOSHOK 2604/2704 Series 0.156" Orifice Block & Bleed 2 Manifold Valves With Hard Seat & Soft Tip, 2704-FFC, Soft Tip, 1/2" NPT Female x 1/2" NPT Female, Steel, 0.156" Orifice 2 Manifold Valve

2604/2704 Series 0.156" Orifice Block & Bleed 2 Manifold Valves With Hard Seat & Soft Tip

• 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

Options and Accessories

• Installed Options and Accessories
  
  • Packing
  • PTFE Manifold Gasket Ring (RG1-TF1)
  • Graphite Manifold Gasket (RG1-GF1)
• Connectors
  
  • 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
  
  • 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.
