VMS120 Security Valve
VMS120 Security Valve
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.
Applications
Technical specifications – Information
Technical data:
|
Material: AISI 304L stainless steel

|
Mounted on the emergency circuit of the glove box
|
|
Mechanical operation, with membrane, without electrical connection
|
|
Ultra-fast response time due to direct reference to cabinet pressure
|
|
Connections: stainless steel flange DN120
|
|
Dry contacts for triggering alarms (pressure fault)
|
|
Security flow 200m3/h
|
|
Higher flow rates up to 500m3/h – contact us
|
|
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).
