The plug valve is mainly used for cutting off, upgrading and changing the flow direction of the medium in the pipeline. It is easy to adapt to a multi-channel structure, so that one valve can obtain two, three, or even four different flow channels, which can simplify the design of the piping system, reduce the amount of valve gates and some connection accessories required in the equipment.…

Tight-sleeve plug valve The tight-sleeved plug valve is usually used in low-pressure straight-through pipelines. The sealing performance depends entirely on the fit between the plug and the plug body. Compress the sealing surface by tightening the lower nut. Generally used for PN≤0.6MPa.…

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.…

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.…

The regulating valve used in low temperature and cryogenic places is called the low temperature regulating 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. …
