Features：
● The ball check are so compact and light that they can be installed in a limited space. They are also easy to maintain, because of minimal internal parts.
● Foot valves in pipelines are subject to water hammer effects and vibrations, which can loosen and damage the threads of the live connection. For this reason it is not recommended to choose a live connection for high temperatures, strong corrosion and other demanding conditions.

As a key component in the fluid control system, the performance of the manual diaphragm valve is directly related to the safety and efficiency of the entire system. As the core component of a manual diaphragm valve, the quality of its condition will directly affect the sealing performance and servic...
Maintenance and maintenance of manual diaphragm valves is the key to ensuring their long-term and stable operation, and regular inspections are the basis of maintenance work. It is crucial to conduct a comprehensive inspection of the valve's appearance, sealing surface, transmission components and c...
In industrial pipeline systems, stop valves are widely used in many fields such as petroleum, chemical industry, electric power, metallurgy and urban construction as a key control equipment. Stop valves are mainly used to cut off, adjust and throttle the medium in the pipeline. Their simple structur...
The superior performance of the stop valve in flow regulation is mainly due to the exquisite design of its valve disc. The valve disc moves linearly along the center line of the valve seat. This movement ensures the close fit of the sealing surface between the valve disc and the valve seat, thereby ...
Our company's Automatic Butterfly Valve sealing structure uses industry-leading elastic sealing materials, including high-performance rubber and polytetrafluoroethylene (PTFE). These materials not only have excellent elasticity and wear resistance, but also can adapt to the chemical properties of a ...
In modern industry, automatic butterfly valves are key equipment for fluid control, and their performance directly affects production efficiency and safety. Our company is committed to the research and development of high-performance automatic butterfly valves, especially in the design of butterfly ...
