Advantages and Disadvantages of Various Valves
Gate Valve: A gate valve is a valve that uses a gate (gate plate) to move vertically along the axis of the passage. It is primarily used in pipelines for isolating the medium, i.e., fully open or fully closed. Generally, gate valves are not suitable for flow regulation. They can be used for both ...Read more -
Information on Check Valve
When it comes to fluid pipeline systems, check valves are essential components. They are designed to control the direction of fluid flow in the pipeline and prevent backflow or back-siphonage. This article will introduce the basic principles, types, and applications of check valves. The basic pri...Read more -
Six Reasons On Damage To The Sealing Surface of Valve
Due to the sealing element’s function of interrupting and connecting,regulating and distributing, separating and mixing media in the valvpassage, the sealing surface is often subject to corrosion, erosion, and wear by the media, which makes it highly susceptible to damage. Key Words：the se...Read more -

Structural analysis (1) This butterfly valve has a circular cake-shaped structure, the inner cavity is connected and supported by 8 reinforcing ribs, the top Φ620 hole communicates with the inner cavity, and the rest of the valve is closed, the sand core is difficult to fix and easy to deform....Read more -
16 Principles In Valve Pressure Testing
Manufactured valves must undergo various performance tests, the most important of which is pressure testing. Pressure test is to test whether the pressure value that the valve can withstand meets the requirements of production regulations. In TWS, the soft seated butterfly valve, it must be carri...Read more -
Where check valves are applicable
The purpose of using a check valve is to prevent the reverse flow of the medium, and a check valve is generally installed at the outlet of the pump. In addition, a check valve is installed at the outlet of the compressor. In short, in order to prevent the reverse flow of the medium, check valves ...Read more -
How to choose concentric flanged butterfly valve?
How to choose flanged concentric butterfly valve? Flanged butterfly valves are mainly used in industrial production pipelines. Its main function is to cut off the flow of medium in the pipeline, or to adjust the flow of medium in the pipeline. Flanged butterfly valves are widely used in productio...Read more -
Why do gate valves require upper sealing devices?
When the valve is fully open, a sealing device that prevents the medium from leaking to the stuffing box is called the upper sealing device. When the gate valve, globe valve and throttle valve are in the closed state, because the medium flow direction of the globe valve and the throttle valve flo...Read more -
The difference between globe valve and gate valve, how to choose?
Let’s introduce what is the difference between a globe valve and a gate valve. 01 Structure When the installation space is limited, pay attention to the selection: The gate valve can rely on the medium pressure to tightly close the sealing surface, so as to achieve the ...Read more -
