The 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 It may only be installed by suitably trained personnel Any legal regulations or regulations issued by authorities must be observed during assembly The ball valve does not contain any parts that can be replaced or repaired by the user The rotary valve may not be disposed of as household refuse All locally valid regulations and requirements must be observed When determining the flow rate characteristic of final controlling elements, the recognised directives must be observed wwwbelimocom T5-R3/R3G en v Subject to changes 1 / 3

2 R3 / R3G Change-over ball valve, 3-way, with internal thread Product features ode of operation The change-over ball valve is operated by a rotary actuator The rotary actuator is controlled by an open-close signal Installation instructions Recommended installation positions Water quality requirements aintenance The ball valve can be installed standing to lying The ball valve may not be installed in a hanging position ie with the stem pointing downwards The water quality requirements specified in VDI 2035 must be adhered to all valves are sensitive control devices In order to ensure a long service life, it is advisable to fit a strainer all valves and rotary actuators are maintenance-free efore any kind of service work is carried out on actuator sets of this type, it is essential to isolate the rotary actuator from the power supply (by unplugging the power lead) Any pumps in the part of the piping system concerned must also be switched off and the appropriate isolating fittings closed (allow everything to cool down first if necessary and reduce the pressure in the system to atmospheric) The system must not be returned to service until the ball valve and the rotary actuator have been properly reassembled in accordance with the instructions and the pipework has been refilled in the proper manner Flow direction Please also ensure that the ball is in the correct position (marking on the stem) A A A = 100% A = 0% A A A = 100% A = 0% Accessories echanical accessories Description Stem heating ZR24-1 (except for R3G) Pipe connector ZR23 2 / 3 T5-R3/R3G en v Subject to changes wwwbelimocom
