BOG safety valves are intended to protect low pressure tanks not covered by PED against vacuums (vacuum breaker) and/or excess pressure. Depending on the version, the valve blow-off can be collected. Servinox is able to design a valve with respect to tank characteristics (diameter, height), resistance (pressure, vacuum) and washing conditions (temperature, flow-rate).


  • Fully autonomous (no external control required for its operation)
  • Different models available according to requirements: Pressure/vacuum (with or without blow-off collection), Pressure only (with or without blow-off collection), Vacuum only
  • Safety valves compatible with hot/cold washing (after validation by the validation tool)
  • Simplified and cost-effective maintenance
  • Low pressure sealing
  • Hygienic design
  • Freeze protection option on request



  • Manufacture and storage of food and non-food products in a controlled atmosphere (dairy products, beverages, waters, creams and other cosmetic products, fine chemicals, etc.)
  • Tanks not covered by PED, where the service pressure is less than 0.5 bar and the service temperature is less than 120 °C
  • Exclusively designed to transport gases
