2 hange-over ball valve, 3-way, Flange, PN 6 Safety notes When etermining the flow rate characteristic of controlle evices, the recognise irectives must be observe. Prouct features oe of operation The open-close ball valve is ajuste by a rotary actuator. The rotary actuator is connecte by an open-close signal. Open the ball valve counterclockwise an close it clockwise. Installation notes Recommene installation positions The ball valve can be installe upright to horizontal. The ball valve may not be installe in a hanging position, i.e. with the stem pointing ownwars Water quality requirements aintenance Flow irection The water quality requirements specifie in VI 2035 must be ahere to. elimo valves are regulating evices. For the valves to function correctly in the long term, they must be kept free from particle ebris (e.g. weling beas uring installation work). The installation of suitable strainer is recommene. all valves an rotary actuators are maintenance-free. efore any kin of service work is carrie 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 concerne must also be switche off an the appropriate slie valves close (allow everything to cool own first if necessary an reuce the system pressure to ambient pressure level). The system must not be returne to service until the ball valve an the rotary actuator have been properly reassemble in accorance with the instructions an the pipeline has been refille in the proper manner. The irection of flow, specifie by an arrow on the housing, is to be complie with, since otherwise the ball valve coul become amage. Please ensure that the ball is in the correct position (marking on the spinle). = 100% = 0% 2 en-gb subject to changes
