Dräger fire protection deluge valves
The deluge valves are able to control highly pressurised water flow in deluge, preaction, pressure reducing and ON/OFF fire protection systems. The double chamber deluge valves (with a fully redundant architecture) are compatible with hydraulic, electric, electro-pneumatic or pneumatic release systems and ensure a low probability of failure on demand. Both single and double chamber valves are available in Nickle Aluminium Bronze with Nickle Aluminium Bronze/ AISI 316L/ Monel K400 trim. All valves are in line with NFPA guidelines with UL listing, SIL 2 and SIL 3 on selected valves.
