Description

Vac Valve 429 SS HTR is an optimized design for high temperature cures where standard valves with silicone rubber seals breakdown. Vac Valve 429 SS HTR is to be used for direct connection to vacuum hoses instead of a complex and expensive coupling system. Vac Valve 429 SS HTR is usable up to 482°C in combination with new high performance graphite seals. This valve can be directly attached to our Airflow 800 or BBH1080 which provide a safe connection for high temperature processes, such as thermoplastics. Graphite seals for high temperature use are easy to replace and can be ordered separately.

Benefits

• Design reduces threaded plug connection and risk of vacuum leakage for high temperature process.
• Optimized solution for use in high temperature applications.
• Economical and compact solution for high temperature processes.
