Darling Muesco make pressure regulating valves are self actuated – spring & diaphragm operated for precise control of pressure for maximum combustion efficiency in commercial installation.These valves has very high flow capacity and very high precise regulation with the help of Pilot. These valves (also referred as Pressure Regulators) maintain the outlet pressure steadily irrespective of varying inlet pressure in the pipeline. These high capacity regulators are used as final control elements for burner application, installed just ahead of burner manifold in industrial furnaces. These high capacity regulators are used for air, nitrogen, natural gas, hydrogen and many other industrial gases. The regulators give very precise downstream pressure and very low fluctuations. The Pilot Operated Regulators gives very precise downstream pressure and very low fluctuations, with precision up to 1/10th of the inlet pressure. They are extensively used as active and monitor control in series for natural gas pressure reducing system.
