ZDLPG high-temperature resistant electric regulating valve, also known as electric high-temperature regulating valve, is a model of electric regulating valve specially designed and produced for high-temperature medium pipelines. The electric high-temperature regulating valve is equipped with a heat sink between the valve body and the actuator to protect the actuator from malfunction or damage caused by high temperature. Electric high-temperature resistant regulating valve is mainly used for temperature control200Gas or liquid medium pipelines.
1ZDLPGOverview of Electric High Temperature Resistant Regulating Valve
ZDLPW electric high-temperature resistant regulating valve is a type of electric regulating valve developed and produced to adapt to high-temperature medium pipelines. Ordinary electric regulating valves are used for applications higher than200When using a medium, high temperature can be transmitted through the valve stem to the actuator, causing damage or short service life of the electric actuator. In order to adapt to these high-temperature operating conditions,Electric high-temperature regulating valveA heat sink is installed between the electric actuator and the valve body. When used for pipeline transportation of high-temperature media, the heat sink can isolate high temperature conduction to the electric actuator, and will not cause damage to the electric actuator due to high temperature conduction. The valve body can be made of carbon steel or stainless steel according to the temperature of the medium transported by the pipeline, and the sealing adopts metal hard sealing to ensure temperature resistance600°.
The electric high-temperature resistant regulating valve, like other electric regulating valve models, can receive signals sent by the controller4-20MaWait for analog signals to control valve opening in order to adjust pipeline medium parameters. Suitable for medium pipelines of various high-temperature gases or liquids.
