Eccentric plug valve is also called flexible cam valve and eccentric ball plug control valve. When the control valve approaches, it has an eccentric rotating spool. When the valve is closed, the bent arm of the valve core is deformed, so that the spherical ball plug of the valve core is in close contact with the valve seat, and the sealing performance is very good. The features of the eccentric pl…

Electric valve is the main accessory electric actuator, namely electric actuator, which is mainly used in power plants or nuclear power plants, because the high-pressure water system requires a smooth, stable and slow process. The main advantages of electric actuators are high stability and constant thrust that users can apply. …

The difference between the parallel double gate valve and the wedge gate valve is that the sealing surface is parallel to the vertical centerline, so the sealing surface of the valve body and the gate are also parallel to each other. The most common type of this kind of gate valve is the double gate type. …

The double gate valve is suitable for the pipeline with water and sewage as the medium as a closed circuit device, and cannot be used for flow regulation or discharge. It is widely used in petroleum, chemical, pharmaceutical, electric power and other industries. It is used to open and close the steam, water, oil and other medium pipelines with a nominal pressure of ≤1.0MPa. We can manufacture para…

The regulating valve used in low temperature and cryogenic places is called the low temperature regulating valve. So in such a special environment, how do we effectively install the cryogenic control valve? The electric low-temperature control valve checks whether the parts of the whole machine are damaged or loose. For the use of media that are harmful to human health, strength, sealing, leakage …

The flow and velocity of the electric regulating valve mainly depend on the diameter of the electric regulating valve. It is also related to the resistance of the electric regulating valve to the medium. At the same time, it has a certain connection with the pressure, temperature and concentration of the medium of the electric regulating valve. …

First find the vibration source. For externally induced oscillations, the control valve should be kept away from the vibration source; eliminate or weaken the vibration intensity of the vibration source; and use methods such as increasing the fulcrum to weaken the vibration of the control valve when deemed appropriate. The vibration caused by the flow of the internal medium should try to reduce th…

The bellows cut-off valve uses a sealed bellows that can be stretched and compressed to replace the packing seal, which can effectively prevent external leakage caused by packing loss. It is generally used for the transmission of highly permeable media, such as valves on hydrogen systems, as long as the bellows is not damaged, there is generally no leakage; while the general shut-off valve is sea…
