Its plug can be cylindrical or conical. In cylindrical plugs, the channels are generally rectangular, while in tapered plugs, the channels are trapezoidal. These shapes make the structure of the plug valve lighter. It is suitable as a cut-off medium and a replenishment medium, and is also suitable for shunting, but sometimes it can be used for throttling according to the nature of the application …

When installing the plug valve, in order to prevent damage to the plug valve and ensure the full performance of the plug valve…

The advantage of plug valve application is that the valve body installed on the top of the whole is equivalent to the ball valve installed on the top of the whole. Compared with two-piece or three-piece ball valve, it is a completely different type and application product.…

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. 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. …
