​Ball valve has many kinds of structure, but basically the same little difference

​In the thermal system, the thermal trap plays a very important role

Gate valves usually have single gate, double gate, wedge, parallel and other structural designs

Valve sealing surface grinding is a key step to ensure sealing performance

​Sealing surface is the most critical working face of the valve, the quality of the sealing surface directly affects the service life of the valve

The electric actuator of valve ‍ is used to control the valve. If the valve cannot be

Pressure valve is a device used in hydraulic system to control and regulate liquid flow pressure.

Because the seal plays a role in cutting and connecting, adjusting and distributing, separating and mixing media on the valve channel, the sealing surface is often subjected to medium corrosion, erosion, wear and easily damaged.

Valves are not only widely used in various industries, but also the use of different environments, and some valves in harsh working environments are prone to problems.

What is the difference between the use of butterfly valve and gate valve?

What defects are prone to valve castings?

Valve common problems High pressure drop

Gate valve leakage cause analysis and treatment measures
