VMS120 Security Valve

Jacomex Solutions

Gsafe

Description

For hazardous atmospheres, safety valves (designed and manufactured by Jacomex) offer reliable, efficient and long-lasting protection for operators and the environment. They were initially developed to ensure the safety of installations in a nuclear environment and have since been used for other applications where the protection of operators is a priority.

These models are designed to operate exclusively on negative pressure glove boxes. They can be mounted on glove boxes under air or under neutral gas.

Technical data

Technical specifications - Information

Minimum required pressure of the extraction network: -1200 Pa

Main functions:

On/off valve (totally closed and airtight in normal operation – fully open in safety mode).
Total enclosure compatibility in depression under purified controlled atmosphere.
Safety flow (speed 0.5-1 m/s) in the event of an accidental breach of containment.
Increased safety flow on a glove box fitted with a vpr/vmr regulation valve (e.g. vmr63 + vms120 = safety flow 250m³/h).
