Products Description:

1.The lined butterfly valves bi-directional flow is possible at maxmium operating pressure. Since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.

2.It features ease of maintenance, repeatable on-off, long life durability.
3.The concentric design is commonly used in the power generation, brewing, water and food industries and suitable for both gaseous and liquid service. Typically applied in chemical/petrochemical process, food and beverage, and pulp and paper etc.

4.Lining material: PTFE, PFA, FEP, GXPO etc.

5.Connection type: wafer, flange, lug etc.
6.Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.

7.Youfumi lined three-way ball valves are available as per the needs of applications in additional sizes and other than standard materials.
