The opening and closing parts of the three way diaphragm valve are a diaphragm made of soft material, which separates the inner cavity from the inner cavity of the valve cover and the driving parts. The diaphragm made of soft rubber or plastic seal has better sealing performance. Because the diaphragm is a vulnerable part, it should be replaced periodically according to the characteristics of the medium. The three way diaphragm valve is used for the medium containing hard suspending material; because the three way diaphragm valve is only contacted with the valve body and the diaphragm, the stuffing box is not needed, the stuffing box leakage problem is not existed, and the corrosion of the valve stem part is not possible.

Structure characteristics
Diaphragm valve is a special form of stop valve;
1, elastic seal opening and closing parts, to ensure no 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 cover are separated by the middle diaphragm, so that the diaphragm above the valve cover, stem parts are not subject to medium erosion;
5, diaphragm can be replaced, low maintenance costs;
6, lining material diversity, can be applied to a variety of media, and has good corrosion resistance.
Parts list: 1, valve body 2, diaphragm 3, valve 4, valve stem 5, valve cover 6, handwheel
