TL42X plunger valve is a speed and pressure regulating valve developed accordance to hydrodynamic characteristics plus summarization of domestic experience in design, manufacture. It has been widely applied in such fields as power stations and water diversion and supply. After improved, this series of flow regulating valves is not only applicable for clear water but also has good tolerance to natural river/lake water and mild sewage. In respect to its design structure and selected materials, it has solved a problem lasting for many years: the flow regulating valve is vulnerable to scaling and jamming with a too large drive unit.

 

Application:

This valve is mainly used to regulate the pipeline medium’s flow and flow form, plus the pipeline network pressure in pipe network systems with water as the medium in water or power plants, diversion works and so on.
