Pressure Control Deluge Valves

This Inbal Valve combines a deluge and a pressure control function in the same valve. The requirement for pressure control is typically associated with a large system where the fire pump is designed for the capacity of several deluge systems. When only part of the deluge system is operated, the delivery pressure to each system should be reduced to meet the components' pressure rating and to prevent flooding by use of excess flow. When several deluge systems operate simultaneously, the pressure control deluge valves ensure balancing of the water pressure resources and efficient use of the overall capacity.
