VMS63 Security Valve for Glove Box

Jacomex Solutions

Gbox

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 for negative pressure glove boxes. They can be mounted on glove boxes under air or under neutral gas.

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 equipped with a vpr/vmr regulation valve (e.g. vmr63 + vms63 = safety flow 100m³/h).
