What type of water based fire protection system will have the proportioning valve?

Explanation:
Foam systems include a foam concentrate that must be mixed with water to form a foam solution. To ensure the concentrate is added at the correct proportion, these systems use a proportioning valve (proportioner) to meter the concentrate into the water supply. Other common water-based systems—deluge, wet-pipe, and dry-pipe—carry only water in the pipes and do not require mixing additives, so they do not include a proportioning valve.
