  • Ordering Process

The opening and closing part of the three-way diaphragm valve is 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 rubber or plastic soft seal has better sealing performance. Because the diaphragm is a fragile part, it should be replaced periodically according to the characteristics of the medium. The three-way diaphragm valve is used for medium containing hard suspended substance; since the medium of the three-way diaphragm valve only contacts the valve body and diaphragm, there is no need for packing box, no leakage of packing box, and no corrosion to the stem.


Design and manufacture: GB122239


Structure length: GB12221, JB1688


Flange joint dimensions: GB4216, JB78
