The valve has been esigne for use in stationary heating, ventilation an airconitioning systems an is not allowe to be use outsie the specifie fiel of application, especially in aircraft or in any other airborne means of transport. Only authorise specialists may carry out installation. ll applicable legal or institutional installation regulations must be complie uring installation. The valve oes not contain any parts that can be replace or repaire by the user. The valve may not be ispose of as househol refuse. ll locally vali regulations an requirements must be observe R en-gb subject to changes 1

2 7..R Safety notes When etermining the flow rate characteristic of controlle evices, the recognise irectives must be observe. Prouct features Moe of operation Flow characteristic The globe valve is ajuste by a globe valve actuator. The actuators are controlle by a commercially available moulating or 3-point control system an move the valve cone, which acts as a mixing evice, to the opening position ictate by the positioning signal. n equal percentage flow characteristic in the flow irection is prouce by the profile of the valve cone. The bypass exhibits a linear characteristic curve. ccessories escription Electrical accessories Stem heating N (45W) Z24-1 Stem heating N (60W) Z24-1- Installation notes Recommene installation positions The globe valve may be mounte upright to horizontal. It is not permissible to mount the globe valves with the spinle pointing ownwars Water quality requirements Maintenance 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. Globe valves an globe valve actuators are maintenance-free. efore any kin of service work is carrie out on the actuator, it is essential to isolate the globe valve actuator from the power supply (by isconnecting the electrical cables if necessary). ny pumps in the part of the piping system concerne must also be switche off an the appropriate shut-off 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 globe valve an the globe valve actuator have been mounte properly in accorance with the instructions an the pipes have 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 valve coul become amage R en-gb subject to changes
