Description of PD Series
- The PD series selector valve is used as a component of the NN100 Fire Extinguishing System. This valve is used for selectively directing the flow of the agent to the separate hazard space when the NN100 system is designed to individually protect multiple hazards.The actuating pressure from the CO₂ actuating cylinder or N₂ pilot cylinder automatically opens a selector valve and the extinguishing agent is discharged through the selector valve.
The inlet and outlet of the selector valve are provided with ISO 7-1 R threads for connection with the piping. As an option, the adapter for NPT thread is available.
There are four sizes of selector valves, PD25KU (25mm), PD50KU (50mm), PD80KU (80mm), and PD100KU (100mm).
