5 8880 / way motorised valves Notes on choice of motor Buschjost offers various valve designs and a choice of DC, synchronous and stepper motors catering for the wide range of applications of the motorised valve and the customer s needs. The mechanical contacts of DC motors make them unsuitable for control functions involving a large number of small adjustments. The C synchronous motors last longer thanks to their absence of contacts. stepper motor has to be used where frequent and/or fine adjustment is required. The following table shows the characteristics of the components used. otor design otor life (running life) (Count 90 cycle) Recommended pulse duration Recommended interval without current during reversal in direction of rotation up to (ms) (ms) > Synchronous motor > Stepping frequency 00 Hz Further drive models and electronic controllers available on request Flow regulation kit available on request Section View ccessories xx, Cartridge Description *00 Valve cartridge 000 otor drive Cheesehead screw Cable socket with metal locking mechanism, Screw terminal, Enclosure and contact bodies made of * These individual parts form a complete wearing unit.

This means interpretation and production are in accordance to engineers practice wellknown in the member countries. The CEsign at the valve does not refer to the ED. Thus the declaration of conformity is not longer applicable for this directive. 08/ Note to Electromagnetic Compatibility Guideline (EC): The valves shall be provided with an electrical circuit which ensures the limits of the harmonised standards EN 000 and EN 000 are observed, and hence the requirements of the Electromagnetic Compatibility Guideline 0/0/EU (00/08/CE) satisfied. without notice, the specifications given in this document.
