  • Gas distribution of medium pressure
  • Supply gas for burners in medium pressure
  • Oven inert
  • Gas supply for safety devices
  • Pressure limiting device (PROTEÉ 431 with RD05)

PRODUCT ADVANTAGES

  • Watertightness in case of bad weather
  • All components comfortably accessible
  • Easy and fast dismantling
  • Simple and heavy-duty
  • Low closing pressure
  • Removable encapsulated valve
