G45J 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.
