【Our Product Advantage】:
1. The butterfly valve can be bidirection sealing,it adopts S type and cone seat or mobile piston seat to assure the ability the reverse pressure.
2. Since the sealing ring is made entirely of metal material, which greatly improves the service life of the Metal-seated Butterfly Valve.
3. Life of opening and closing is above 25000 times.
4. Sealing material is made of metal , but not rubber and PTFE series,so our valve can adapt to wide temperature range, from -196 to 700 ℃.
5. Metal-seated Butterfly Valve can be used for wide range media such as particle material.
6. This valve is characterised by high temperature resistance,high pressure resistance,corrosion resistance and wear resistance,etc.
