Three-way diaphragm valve uses
three-way diaphragm valve purposes: This valve is designed to control non-corrosive or generally corrosive media, the body cavity surface without lining or covered with a variety of rubber to choose from, suitable for different operating temperatures and fluid pipe road.
Three-way diaphragm valve test
lining: Spark
testing and inspection according to GB / T13297 standard
Nominal pressure: PN (Mpa)
Body: PN × 1.5
Seal: PN × 1.1
Three-way diaphragm
valve Diaphragm valve is a special form Of the globe valve;
1, the elastic seal of the opening and closing pieces to ensure that no internal leakage;
2, streamlined flow channel, making the pressure loss is small;
3, there is no stuffing box, so there is no leakage;
4, spaced above the diaphragm such that the bonnet, the stem parts from erosion of media;
5, the diaphragm can be replaced, low maintenance costs;
6, diversity lining material, may be applied to a variety of media, and has good corrosion resistance .
