Wesman Oil Pressure Regulating Valves reduces oil line pressure to a constantly maintained outlet pressure despite variations in flow rate. These regulators can be used with inlet pressure up to 250 psi and temperature up to 150 deg C. Supply oil to burner at a constant pressure at all operating condition. Avoid buildup of pressure which occurs upstream of Ratiotrol and other equipment at turn down condition. Helps setting of burners and keeps the setting for all conditions. Ensures exact flow of fuel to the burner. Can be set different pressure to the individual or zone burners depending on process requirement. Steady pressure to burner inlets from variable pressure oil supply. Application: Heat treatment furnaces, non-ferrous melting furnaces, kilns, ovens, air heaters, dryers, chemical processing plants.
