The Inbal Pressure Control, Remote Resetting, Electrically Actuated Deluge Valve is specifically designed for use in fire protection systems which require pressure control, actuated by a remote resetting electric detection and release system. The Inbal Pressure Control, Electrically Actuated Deluge Valve, when in operation, automatically reduces a higher inlet pressure to a preset delivery pressure which remains steady and unaffected by the variations or fluctuations in the inlet line pressure.
The Inbal Pressure Control, Electrically Actuated Deluge Valve is used for automatic or manual operation. Electric activation of the Inbal Deluge System requires a solenoid valve controlled by a control (fire alarm & releasing) panel either manually or by heat, smoke, or flame detectors. When the detection system operates, the control panel activates the Solenoid Valve to open. When the Solenoid Valve is actuated either automatically or manually or when a manual release station is operated locally or remotely, the Inbal Deluge Valve opens and water flows from all open sprinklers and/or nozzles on the system.
While the valve operates, the deluge system pressure is maintained at the preset level within a narrow range. If the downstream pressure changes slightly, the pilot control responds immediately to modulate the Inbal Valve for the preset pressure.
The use of the Inbal Pressure Control Deluge Valve balances the distribution of the water capacity available, throughout the system and prevents a higher demand from the areas which are of lower altitude or are located closer to the pressure source. Thus, the total system demand is balanced and the excess flow through the system with high pressure water supplies is reduced to the desired level. The adjustment of the valve’s delivery pressure can be easily modified at the site.
After operation, the Inbal Valve can be reset by remote control, saving the need to approach the Deluge Valve for resetting. The trim includes all the pilot valves, accessories, and fittings to provide for proper operation, either at vertical or horizontal installation. Standard material Inbal Deluge Valve is rated to 300 psi (21 bar) working pressure. The Solenoid Valve rating should be at least as the maximum designed delivery pressure. Inbal Pressure Control Deluge Valves are available in sizes 11⁄2″ (40 mm) to 12″ (300 mm) with threaded, flanged, grooved, or wafer ends.
The only moving part in the Inbal Valve, when it operates, is the reinforced sleeve which forms a drip tight seal with the corrosion resistant core. It has a smooth opening to prevent any water hammer in the piping system.
The unique design of the Inbal Valve and the pilot control and variety of materials and coatings make the Inbal Pressure Control Deluge Valve suitable for use with brackish or sea water similar to those found in chemical and petrochemical facilities or in offshore platforms.
