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. At the same time, ZhengFeng has always taken innovation as the precondition and has been constantly innovating new products, such as intelligent pressure control valve, pressure management system and other world-leading ideas, which have also created an absolute share of the tap water market in big cities like Beijing and Shanghai in China.
