What are the specific characteristics of the shut-off solenoid valve?

There are flow regulation or pressure regulation solenoid valves. However, the requirements for adjustment accuracy are not high. With the development of ball valves and butterfly valves, the price of solenoid valves has replaced part of the application of globe valves.

Moreover, the diameter of the pipeline is relatively small, and its selection principle is: the price of the globe valve solenoid valve should be used on the pipeline or device of the high temperature and high pressure medium. Such as thermal power plants and nuclear power plants. The price of solenoid valves on high temperature and high pressure pipelines in petrochemical systems. The price of solenoid valves in some pipelines where the pressure loss of convection resistance is not considered, such as the pipeline with a nominal passage of ≤50mm, but from the characteristics of the globe valve itself, the right-angle solenoid valve pulse valve.

Small valves can choose needle valves, instrument valves, sampling valves, pressure gauge valves, etc. It is easy to choose a direct-flow stop valve or direct-flow throttle valve with a separate valve body, a removable seat, and a cemented carbide seal pair. .

The globe valve solenoid valve is one of the most widely used valves. The high pressure angle globe valve or the high pressure angle throttle valve should be used for small fertilizers and large fertilizers in synthetic industrial production. The price of solenoid valve should be used in the desiliconization workshop and the pipelines that are easy to coke in the production of alumina Bayer process. For the water supply and heating projects in urban construction, the nominally smaller pipelines can be used. Plunger valve.
