Generation Boiler plants District heating plants Refrigeration plants Distribution Heating groups Ventilation and airhandling units Engineering notes Mounting location Dirt trap Cavitation Preferably mount the valves at the return, as the temperature is lower there and the stem sealing gland is less strained. Mount a dirt filter or dirt trap before the valve to ensure proper functioning, and a long service life of the valve. Remove dirt, welding beads, etc. from the valves and pipes. Cavitation can be avoided by limiting the pressure differential across the valve depending on the medium temperature and prepressure.

8 Mounting notes Mounting position Indoors Outdoors Commissioning notes Mounting positions apply to both 2 and 3port valves. Note Function check The valve may be put into operation only if actuator and valve are correctly assembled. Ensure that actuator stem and valve stem are rigidly connected in all positions. Valve Throughport A AB Bypass B AB Valve stem extends Closes Opens Valve stem retracts Opens Closes Maintenance notes Valves are equipped with maintenancefree, continuously lubricated stem sealing glands. See page 13 for replacement stem sealing glands. When servicing valves or actuators: Deactivate the pump and turn off the power supply Close the shutoff valves Fully reduce the pressure in the piping system and allow pipes to completely cool down Disposal If necessary, disconnect the electrical wires. Due to the different types of material used, the valve must be disassembled prior to disposal. Special handling of certain valve components may be required by law or may be sensible from an ecological point of view. Local and currently valid legislation must be observed. Warranty Applicationrelated technical data are guaranteed only when the valves are used in connection with the Siemens actuators listed under Equipment combinations, page 3. When used with actuators of other manufacture, any warranty by Siemens becomes void. 8 / 14 Siemens 2 and 3port valves with flanged connections, PN 10 CE1N4402en Building Technologies
