Techflow TE-Series Extended Stem Cryogenic Valves
Techflow TV-Series Vacuum Jacketed Cryogenic Valves
Bulk Tank Withdrawal Valve

Features

  • Self-aligning, PCTFE seat designed for flexibility and solid closure at cryogenic temperatures.

  • Port on bonnet for relief valve, purge valve, or pressure gauge installation.

  • Pneumatic or electric actuators available for automated operation.

  • ASME B16.34 code compliant available.

  • One year warranty if sold separately.

  • MODULAR SHUTOFF VALVES AVAILABLE FOR UPGRADED SAFETY

Benefits

  • 20x less cryogen loss versus non-vacuum jacketed cryogenic valves equates to lower operation costs.

  • Bubble tight closure means tighter seal at cryogenic temperatures preventing possible equipment problems.
  • Vacuum jacketed insures safe to touch during use.
  • Low torque for easy on/off operation.
  • Quick and easy seal replacement reduces downtime.

Applications

  • Shut Offs

  • Pipe and Equipment Isolation

  • Point-of-Use Valves

  • System Expansion / Re-Routing Connections

  • Cold Boxes
