These kind of facilities have many processes to produce some products that are very flammable (oils and flour). Also Oils are  storaged in tanks and flour in warehouses. How can I protect this kind of occupancy? Can I use low expansion foam systems?   Best regards,

Good morning, I'm writing to ask for the following clarification: the control valve of a wet system can be installed inside the protected area by the sprinkler system? (specifically insiede the warehouse area). Thank you in advance.
