Products Decription:

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.

YFM high performance butterfly valve advantages

Feature 1:There is three O-rings on the uper stem combined with the gland which ensure more better sealing performance, and lighter torque;

Feature 2:Extended seat can provide more effective sealing performance;

Feature3:The body is splited and could be adjusted by hex screw;

Feature 4:The elastomer backing supports the seat will not be deformed under working pressure;

Feature 5:The O-ring is also applied at both the upper and lower stem, which can ensure the seal between the disc and seat.
