The Inbal Pressure Reducing Valve series 700D-01R01 is specifically designed for pressure regulating applications in fire protection systems. The Inbal 700D-01R01 Valve auto- matically 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 series 700D-01R01 consists of the Inbal Valve which is a pressure operated, sleeve actuated, axial valve and a pressure reducing pilot control. The Inbal Pressure Reducing Valve maintains the downstream pressure within a narrow pressure 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 Reducing 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 delivery pressure could be easily modified at the site.
Standard material Inbal Pressure Reducing Valves are rated to 300 psi and are available in sizes 11⁄2″ (40 mm) to 12″ (300 mm) with threaded, flanged, and 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. The unique design of the Inbal Valve and the pilot control, as well as the variety of materials and coatings make the Inbal Pressure Reducing Valve suitable for use with brackish or sea water similar to those found in chemical and petrochemical facilities or in offshore platforms.
