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

  • Research and R&D laboratories
  • Pharmaceutical and Medical sectors
  • Nuclear sector
  • Heavy Industry

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.
