Features:
DIN F4 soft seal gate valve introduced foreign advanced technology produced by DIN standard gate valve. Overcome the general gate valve sealing inspection ,elastic fatigue ,easy to rust and other defects . DIN standard soft seal gate valve has the characteristics of light on / off, reliable sealing , good elastic memory and long service life . can be widely used in tap water sewage , construction ,food ,power , and other fluid pipeline as a closure device .
1. The gasket of the vulnerable parts, the sealing material is EPDM rubber, which is reliable and has a long life.
2. The whole gate is covered with adhesive, its good covering performance and accurate geometry size, to ensure reliable sealing.
3. The valve body bonnet is made of ductile iron material, light weight and easy installation.
4. The bottom adopts the same flat-bottom valve seat design as the water pipe, which does not produce debris deposition and is reliably sealed.
5. The inner and outer cavity is made of non-toxic epoxy resin to prevent corrosion and rust, which can not only be used for raw
