- 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).
Application :
- Watertightness in case of bad weather.
- All components comfortably accessible.
- Easy and fast dismantling.
- Simple and heavy-duty.
- Low pressure closing.
- Stainless steel adjustment screw.
