The new coil Family D36 provides the basis for Bosch Rexroth ‘New Solenoid Concept’ Cartridge Valves with optimized technical performance, suited for broader bandwidth of applications. The rugged design allows the valve equipped with this coil system to be used also in the harshest environments in mobile machinery applications. The coils exceed IP69K standard, are tested under harsh vibration and temperature cycle conditions and provide an excellent long-term operation. The fully plastic external housing design provides chemical resistance against corrosion induced by salt-spray or chemicals (e.g. agriculture).
