WL160609 SCR Solenoid Valve Application A SCR solenoids finds wide applications in precise DEF injection, in processing of exhaust gases in diesel engines. These devices serve to control the amount of Diesel Exhaust Fluid supplied to SCR catalyst system. The SCR Solenoid is frequently found in automotive sector in heavy trucks, buses, pick up trucks, commercial vehicles and passenger diesel vehicles. Agricultural equipment including various types of tractors and harvesters, where there is a significant usage of diesel engines, cannot work without SCR solenoid. Solenoids for SCR are widely used...
