Brief Introduction.
This Type of PRV is a new product developed by us,through our continuous improvement,it already becomes a substitute for the same kind of products abroad,its special character is that working area of memberance is larger than other spring diaphragm pressure reducing valve,therefore,it can sensor the micro pressure change from downstream(such as 0.01 Mpa) and make immediate regulating.As its good performance of reducing and sustaining pressure,it is widely usded for the pipelines which inlet pressure and outlet flow change much.Field of Application.
