  • The industrial valve is a kind of common component in electric actuator. The typical industrial valve is composed of butterfly valve, ball valve as well as plug valve. Due to the different classifications of industrial valve, the industrial valve working principles are various.
  • The Industrial valve is the general name of several valves such as ball valve, plug valve as well as butterfly valve. And it is a kind of component for devices like electric actuator or pneumatic actuator. Due to the presence of new technology, the Industrial valve is able to possess higher performance and wider applications.
  • The Industrial valve is a crucial component of electric actuator. It is used to connect two pipelines and control the fluid. Although having some problems in technology, the Industrial valve still has its own application due to the advantages and wide functions.
  • Principles of selecting gate valve, the gate valve should be the first choice when shut-off valves need to be used for pipelines. Normally, globe valves are a little bit expensive than gate valves, but a little cheaper than metal-sealed ball valves, seldom used as shut-off valves for main pipelines.
  • Common manual valves, including ball valve, gate valve, globe valve, butterfly valve, plug valve, etc., are the most widely used valves. Their handwheels or handles are designed according to ordinary manpower, taking into account the strength of the sealing surface and the required closing force.
  • In recent years, with the continuous improvement of China's comprehensive national strength, the development of China's marine industry has also achieved rapid progress. In this context, the shipbuilding industry has drawn much attention.
  • Due to the relatively large variety of valves used in the marine's pipelines, this creates difficulties in preparing and revising the appropriate standards for valves. Another aspect is that the use of valves in current marine pipelines in China is mainly based on manual valves such as a globe valve and gate valve. Such industrial valves are still relatively insufficient in terms of weight, volume, and sealing.
  • The industrial gate valve refers to a valve in which the closing part (gate) moves in the vertical direction of the center line of the passage. The gate valve can only be used for full opening and full closing in the pipeline, and cannot be adjusted and throttled. The gate valve is a kind of valve w
  • What are the technical difficulties of high-temperature three-eccentric metal hard-seal butterfly valves? What problems have been encountered in design and development? How to solve them?
  • The wafer check valve is applied to various lines of Class150~Class2500 and PN20~PN420 to prevent the medium in the pipeline from flowing back. Different materials are used, and the check valve can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
