Product details

G45J Liner DC diaphragm valve structure features
1, the elastic seal of the opening and closing pieces to ensure that no internal leakage; 
2, streamlined runner, making the pressure loss is small; 
3, there is no stuffing box, so there is no leakage; 
4, the valve body And the cover is separated by the middle diaphragm, so that the valve cover above the diaphragm, valve stem parts from erosion of the medium; 
5, the diaphragm can be replaced, low maintenance costs; 
6, the diversity of lining material can be applied to a variety of media, and has Good corrosion resistance.
