Vacuum Jacketed Cryogenic Valves
Manufactured by Technifab to Provide Minimal Cryogen Losses
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.
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.
