.
. Siemens regulating valve 3 series technical parameters
. Rated pressure:
. Connection method: flange< . Caliber:
. Medium temperature: -℃
. Rated stroke:-
. Material: valve body, ductile iron, stem, valve seat, valve plug, stainless steel
.
. Siemens control valve 3 series uses
. Used as control or stop valves in boilers, district heating and refrigeration equipment, cooling towers, heating units and air conditioning units
. Suitable for closed Type or open piping system (pay attention to avoid cavitation)
.
. Engineering precautions
. Installation position: The valve should be installed on the return pipe, where the temperature is lower and the sealing The load is also lower
.. When the valve is used as a steam valve, it must be installed in reverse
. Dirt collector: Install a filter or dirt collector in front of the valve to ensure the valve adjustment function, and Long service life. Remove dirt, welding slag, etc. from valves and pipelines
. Cavitation: Cavitation erosion can be avoided by limiting the pressure difference before and after the valve according to the relationship between medium temperature and pressure.
