Wafer full rubber lined butterfly valve is fully NBR, EPDM,VITION rubber lined on the body and disc to avoid medium contact. Wafer full rubber lined butterfly valve is widely used in water source projects, urban water supply and drainage, sewage treatment, electric power, petroleum, petrochemical, heat supply, shipbuilding,medicine and metallurgy industries. Valves used for regulating or cutting off liquids in pipelines.

Wafer full rubber lined butterfly valve feature:

1. Easy to open and close quickly, can often operate.

2. Small shape, short structure, suitable for large caliber valves.

3. Rubber sealing surface, low pressure sealing performance is good.

4. It can transport mud, at the mouth of the least liquid accumulation.

5. When the channel is fully open, the flow area is large and the fluid resistance is small.
