DIN F4 gate valve is mainly divided into NRS non-rising stem and RS rising stem (OS&Y). The main material is ductile iron. When the whole rubber-coated valve plate is closed, the deformation compensation effect achieves a good sealing effect, which overcomes the poor sealing and water leakage of general gate valves. and rust
