2 D6..N Wafer type butterfly valves Safety notes Prouct features! Moe of operation Manual overrie The butterfly valve has been esigne for use in stationary heating, ventilation an air conitioning 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. It may only be installe by suitably traine personnel. Any legal regulations or regulations issue by authorities must be observe uring assembly. The butterfly valve oes not contain any parts that can be replace or repaire by the user. The butterfly valve may not be ispose of as househol refuse. All locally vali regulations an requirements must be observe. When etermining the flow rate characteristic of final controlling elements. the recognise irectives must be observe. In orer to avoi water hammers in the piping system, the isc is to be opene an close slowly. The butterfly valve is opene or close completely by an open-close rotary actuator. Continuous rotary actuators are controlle by a commercially available controller an move the valve iscs into any position esire. The isc mae of stainless steel is presse into the soft-sealing EPDM seat by a rotary movement an ensures leakage rate A (tight). The flow rate losses are slight in open position an the k vs value is high. Manual throttling or shut-off can be carrie out with a lever or a worm gear (see «Accessories»). With lever ( ): Ajustable in 0 ratchet steps with position inication (0 = 0 ; 9 = 90 ). With worm gear ( ): Steplessly ajustable (self-locking) with position inication. Installation instructions Recommene installation positions The butterfly valves may be mounte from vertical to horizontal. The butterfly valves may not be installe in a hanging position i.e. with the stem pointing ownwars Water quality requirements Maintenance Recommenation utterfly valves shoul rive once per month a full cycle. The water quality requirements specifie in VDI 05 must be ahere to. utterfly valves, rotary actuators an mechanical accessories are maintenance-free. efore any kin of service work is carrie out on actuator sets of this type. it is essential to isolate the rotary actuator from the power supply (by unplugging the power lea). Any pumps in the part of the piping system concerne must also be switche off an the appropriate isolating fittings close (allow everything to cool own first if necessary an reuce the pressure in the system to atmospheric). The system must not be returne to service until the butterfly valve an the rotary actuator have been properly reassemble in accorance with the instructions an the pipework has been refille in the proper manner.
