VMS63 Security Valve for Glove Box
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.
Applications
Technical Specifications
Technical specifications of the security valve:
|
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: ISO KF DN50
|
|
Dry contacts for triggering alarms (pressure fault)
|
|
Security flow 50m3/h
|
|
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 equipped with a vpr/vmr regulation valve (e.g. vmr63 + vms63 = safety flow 100m3/h).
Compatibility
This equipment can be installed on the following glove box models
Glove box designed for research and industry for all applications < 1PPM H2O – O2
Adjustable glove box under filtered air for protection of the operator and / or the environment.
High security isolator under neutral gas filtered in depression or overpressure under filtered atmosphere.
