2 an Drive lectrohydraulic an Drive Systems Walvoil an Drive is a new range of vehicle cooling systems based on external gear motors; these types of motors are widely used in modern hydraulics due to their high performance, long life service and low maintenance costs. n electrohydraulic an Drive offers significant advantages if compared with traditional solutions with electric or belt drives. Maximum performance is achieved by coupling the an Drive with the Walvoil D4W electronic control units, fully programmable.

3 M Variable speed an Drive system Motor with a proportional pressure relief valve and an anti-cavitation valve integrated in the rear cover. The max speed of the motor can be controlled independently by the engine speed for optimal performance and lower energy consumption. In case of power failure the max speed is achieved. In case of sudden engine stop, the anticavitation valve prevents any fan damage.

7 ccessories Temperature sensor Range of sensors made of sintered semiconductor material particularly sensitive to temperature; it allows to obtain large variations in resistance in proportion to small temperature variations. The sensor is available with different electrical connections (able, Delphi Metri Pack, MP junior power Timer, Deutch DT4).
