Siemens steam temperature control valve supplier

Siemens steam temperature control valve for plate heat exchanger units

Siemens steam temperature control valves for grain dryers, drying machines, and heat exchange units are used for automatic temperature control of grain dryers, grain drying towers, steam dryers, starch drying equipment, and other equipment that require drying and drying using steam as the heat source.
Widely used as an automatic temperature control valve in boilers, district heating and cooling equipment, cooling towers, heating units, air conditioning units, various heat exchange units, heat exchangers, and heat exchange stations, suitable for closed or open piping systems.

The steam temperature control valve is composed of a German SIEMENS original controller RWD60, a German SIEMENS original spring reset actuator SKD62, a German SIEMENS original sensor QAE21, and a balanced ductile iron valve body.
The electric steam temperature control valve with this configuration has the function of automatically closing the valve when the power grid suddenly loses power. In the event of a power outage, the Siemens actuator will use a spring reset to automatically close the valve, cut off the heat source, and effectively protect the heating equipment and pipeline network from high temperature damage.
It can be used as a 24-hour unmanned heat exchange station and automatic temperature control in air conditioning rooms, with high control accuracy and stable operation, effectively solving the problem of frequent manual opening and closing of shut-off valves to control heat sources. Can effectively save energy by 10% ... 50%.

The electric temperature control valve body adopts the single seat structure balanced valve produced by our company. It is equipped with a pressure balancing device inside, which can offset the thrust generated by the high pressure drop of the valve core, effectively solving the problem of high pressure on-site shut-off force, thereby reducing the load on the actuator and extending its service life. According to the actual situation of steam field in China, heat transfer isolation measures have been taken to better adapt to the on-site use conditions in China. Suitable for chilled water, low-pressure hot water, domestic hot water, high-pressure hot water, seawater, hot oil, saturated steam and superheated steam in open or closed circuits, medium temperature -25-350 ℃, caliber: DN15-DN250.
