Commonly used valve body material code description
Valve body material code description: The material of the valve body should first consider the physical properties (temperature, pressure) and chemical properties (corrosiveness) of the working medium. At the same time, you should also understand the cleanliness of the medium (with or without solid particles). In addition, it is necessary to refer to the relevant […]
Code of valve sealing or lining material
The sealing surface of the valve mainly refers to the contact surface of the valve disc and the valve seat. The sealing element plays the role of cutting off and connecting, adjusting and distributing, separating and mixing the medium on the valve passage, and improving the quality and service life of the valve sealing surface. […]
Types and selection of electric valves
Types of electric valves: Electric valves are valves driven by electric energy, mainly composed of electric actuators and various types of valves. Because the electric valve is easy to use and can be operated when the power is turned on, it is the longest-used type of automatic control valve. There are many types of electric […]
Lining material and its application scope of fluorine lined valve
Description of lining material of fluorine-lined valve With the maturity of the fluorine lining process, the varieties of fluorine lining valves are becoming more and more abundant, including fluorine diaphragm valves, fluorine butterfly valves, fluorine ball valves, fluorine check valves, fluorine globe valves, and fluorine filters. The biggest advantage of fluorine-lined valves is to control […]
Classification and selection of fluorine-lined valves
Fluorine-lined valves, anti-corrosion valves, corrosion-resistant special valves Introduction to fluorine-lined valves and corrosion-resistant valves: Fluorine-lined valve, also known as fluorine-lined plastic corrosion-resistant valve, is a method of molding (or inlaying) polytetrafluoroethylene resin and placing it on the inner wall of the valve pressure part or the outer surface of the valve inner part. (The same […]
The difference and selection of electric valve and pneumatic valve
With the progress and continuous reform of the times, my country’s valve products have also been innovated with the change of the times. At present, in the valve market where environmental protection and safety are increasingly demanded, the use of automatic control devices such as electric valves and pneumatic valves is gradually becoming impossible Optional.

It is generally used for The mutual connection between the shaft and the shaft is also used for the connection between the pipe ends; […]
Comparison table of valve diameter and medium flow rate
It is well known that the flow rate and flow rate of the valve mainly depend on the diameter of the valve, and also related to the resistance of the valve structure to the medium. At the same time, it has a certain internal connection with various factors such as the valve pressure, temperature and […]
The matching function and principle of pneumatic valve accessories
Pneumatic valve is an actuator that uses compressed air to drive and operate the valve. Its opening and closing speed is relatively fast. It is often used for fast two-position cut-off and can also be used to adjust flow. Because it mainly relies on air to perform operations, so it has high practicability in flammable […]
