This compensates for the flow resistance of the heat exchanger or radiator, so keeping the overall flow rate, V 100 as constant as possible.

6 We recommend installation in the return pipe, as the temperatures in this pipe are lower for applications in heating systems, which in turn, extends the stem sealing gland s life. Recommendation: lways use a strainer upstream of the valve to increase the valve s functional safety. Mounting notes oth valve and actuator can easily be assembled at the mounting location. Neither special tools nor adjustments are required. The valve is supplied with Mounting Instructions Orientation Commissioning notes Commission the valve only if the manual knob or actuator has been mounted correctly. Manual adjustment The straight-through path can be opened electrically via the actuator, or manually. With three-port valves, this throttles or closes bypass. Manually, path can only be opened to 70 % (bypass closes to 30 %). The valves with k vs values 10, 16 and 25 can be fully opened whereas the bypass can be fully closed. The valves are closed by a return spring. Maintenance V..P45.. valves require no maintenance.. Warning When doing service work on the valve / actuator: Deactivate the pump and turn off the power supply Close the shuttoff valves Fully reduce the pressure in the piping system and allow pipes to completely cool down If necessary, disconnect the electrical wires. efore putting the valve into operation again, make certain the manual knob or the actuator is correctly fitted. Stem sealing gland Disposal The stem sealing gland cannot be exchanged. In the case of leakage, the entire valve must be replaced. Contact your local office or branch. Do not dispose of the device as household waste. Warning Due to the tensioned spring return, valve disassembly may result in flying parts causing possible injury. Only authorized staff may disassemble valves with tensioned spring return! Disposal Special handling of individual components may be mandated by law or make ecological sense. Observe all local and currently applicable laws and regulations. 6/10 uilding Technologies
