Description
The Inbal Pressure Reducing Valve is specifically designed for pressure regulating applications in fire protection systems. The valve 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. This valve is a pressure operated, sleeve actuated, axial valve and a pressure reducing pilot control.
The valve maintains the downstream pressure within a narrow pressure range. If the downstream pressure changes slightly the pilot control responds immediately to modulate the pressure reducing valve to the preset pressure. The use of this 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.
