VPR120/VMR120 Regulating Valves
VPR120/VMR120 Regulating Valves
For hazardous atmospheres, control valves (designed and manufactured by Jacomex) provide 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. In addition, they reduce internal air turbulence and the flow indicator indicates the level of clogging of the HEPA filters.

Main functions
- Automatic regulation of the (de)pressure of the glove box.
- Instant readjustment of the (de)pressure during movement/handling (gloves) and for any other pressure variation caused by an internal process.
- Automatic compensation for progressive clogging of HEPA filters.
- Safety flow rate (speed 0.5-1 m/s) in the event of accidental rupture of containment in a large opening (round bags for example).
