VMS120 Security Valve

SKU:


VMS120 Security Valve Suitable for G[Safe] glove boxes Selling per unit.



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:




  • 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).
