Control Valve

ZhengFengbalanced trim control valves are widely used in water supply and drainage control systems in the global building market. As one of the top three brands of water system valves produced in China, ZhengFeng has strict requirements on the materials used for parts and the technological process, For example, all the copper standard parts and the copper inner parts, because ZhengFeng has mastered the source of copper raw materials, to ensure the reliability of the copper material from the very beginning of finishing, and in the casting process, it will go through a series of detection methods such as pre-furnace analysis and spectrometer material testing to ensure the safety of the material.

At the beginning of the finishing all copper fittings and internal parts are through the preciseness of the NC equipment processing, prevent the dimensional deviation caused by human reason, and in the machining process and the process is completed, will regularly with the analyst is responsible for inspection the size of the product and processing roughness, which further guarantee is abundance to all parts of the quality control.

For the control valve, performance and practicality are the main components, Valves for functions such as pressure reducing valves and pressure relief valves can cause blowouts, flooding pump rooms and other more serious effects if performance issues arise. Therefore, it is ZhengFeng's rigorous attitude to the product that also makes it obtain 100% reliability and no maintenance rate in the control valve field.
