R2..xx-S.. Safety notes! The ball valve has been designed for use in stationary heating, ventilation and air-conditioning systems and is not allowed to be used outside the specified field of application, especially in aircraft or in any other airborne means of transport. Only authorised specialists may carry out installation. ll applicable legal or institutional installation regulations must be complied with during installation. The ball valve does not contain any parts that can be replaced or repaired by the user. The ball valve may not be disposed of as household refuse. ll locally valid regulations and requirements must be observed. When determining the flow rate characteristic of controlled devices, the recognised directives must be observed. Product features Principle of operation Flow characteristic The characterised control valve is adjusted by a rotary actuator. The actuator is controlled by a commercially available modulating or 3-point control system and moves the ball of the valve the throttling device to the position dictated by the positioning signal. Open the characterised control valve counterclockwise and close it clockwise. Equal percentage flow control is ensured by the integrated characterising disk. Installation instructions Recommended installation positions The ball valve can be installed upright to horizontal. The ball valve may not be installed in a hanging position, i.e. with the spindle pointing downwards. 90 90 Water quality requirements Maintenance Flow direction The water quality requirements specified in VDI 35 must be adhered to. Characterised control valves are regulating devices. The use of dirt filters is recommended in order to prolong their service life as modulating instruments. all valves and rotary actuators are maintenance-free. efore any kind of service work is carried out on the actuator, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable). ny pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow everything to cool down first if necessary and reduce the system pressure to ambient pressure level). The system must not be returned to service until the characterised control valve and the rotary actuator have been properly reassembled in accordance with the instructions and the pipeline has been refilled in the proper manner. The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the ball valve could become damaged. Please ensure that the ball is in the correct position (marking on the spindle). = % = 0% ccessories Description Mechanical accessories Pipe connector for characterised control valve DN Pipe connector for characterised control valve DN Pipe connector for characterised control valve DN Pipe connector for characterised control valve DN 32 Pipe connector for characterised control valve DN Pipe connector for characterised control valve DN Data sheet name ZR23 ZR23 ZR23 ZR2332 ZR23 ZR23 2 R2..xx-S.. en v..0 2.
