The Pre Action Deluge valves are designed to minimize the friction loss inside and inner parts such as clapper are made of cast bronze to offer excellent corrosion and pressure resistance. The pre-action system is a sprinkler system employing automatic sprinklers that are attached to a piping system that contains air that might or might not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers. In a pre-action sprinkler system there will normally be supplementary detection devices and closed automatic heat sensitive sprinklers fixed to the air or nitrogen-filled system piping in the protected area. An advantage of closed automatic heat sensitive sprinklers used in pre-action systems is that when opened by a localized heat source, they will only let water into the area where the fire is. This prevents soaking up of large areas of the protected areas might be with a deluge system and the water damage is typically restricted to the area of the fire only. Pre-action sprinkler systems keep the piping in the protected are dry. Instead of water, the sprinkler piping is filled with air or nitrogen. This makes some pre-action systems the system of choice for protecting freezing areas such as refrigeration installations.
