A ball valve is a valve with a ball as a closing part, which is mainly composed of a valve body, a valve seat, a ball, a valve stem, a handle (or other driving devices, such as electric actuators, pneumatic actuators or hydraulic actuators). The valve stem drives and rotates around the axis of the …

Working principle of butterfly valve: The butterfly valve is a kind of valve that is opened and closed according to the rotating valve stem while driving the disc plate to rotate. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, mainly rotating the disc plate 90C; for …

What is valve corrosion? Corrosion of the valve is usually understood as the damage to the metal material of the valve under the action of a chemical or electrochemical environment. Since the “corrosion” phenomenon occurs in the spontaneous interaction between the metal and the surrounding environment, how to isolate the metal from the surrounding environment …

With the rapid development of many industrial fields in our country, industrial automation has completely replaced manual operating systems, especially the use of various automatic control valves. With its unique structural characteristics, electric butterfly valves have become one of the most used valve types. First, the scope of application is also the most extensive. However, …

The electric three-way control valve has been used more and more widely due to its high adjustment accuracy, stable and reliable action, and the unique characteristics of one valve for multiple uses, and has been involved in many fields. However, users often encounter many problems in the actual application process, which has a lot to do with the …

Ball valve is currently the most widely used mechanical product in all valve markets. It is mainly composed of valve body, valve seat, ball, valve stem and transmission device. The actuating device drives the core to rotate to achieve the function of switch or adjustment. In the chemical, environmental protection, water treatment, urban construction, machinery, …

一.Overview of electric ball valve: The function is a kind of pipeline pressure component for industrial automation process control,  usually used for remote opening and closing (connecting and cutting off the medium) control of  the pipeline medium. Features: It adopts an integrated structure and can control the operation with single-phase  power supply AC220V and DC …

The performance of the high pressure casting globe valve:Because the change of the valve seat passage of the high-pressure casting globe valve is proportional to the valve flap stroke. The opening or closing stroke of the valve stem of the high-pressure shut-off valve is relatively short, and it has a very reliable cut-off function, and …
