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
Reliable, absolute tight sealing at all critical points (upstream/downstream, shaft and flanges).
“Locked-In” liner design provides for tight shut-off at full differential pressure with the downstream flange removed.
No required maintenance (no adjustable packing gland, permanently lubricated).
Low pressure drop (smooth profile liner and disc).
Minimal required torque (PTFE filled sleeve bearings).
Strong internal shaft-disc connection (splined shafts <24in.,parallel keys>24in.).
Blowout proof shafts.
Economical use of body materials (valve body is totally encapsulated by the inner lining).
Minimal overall dimensions and weight.
Bi-directional flow and tight shut-off characteristics.
Sanitary construction (no fluid or particulate material traps).
Complete compatibility with a wide range of manual,pneumatic, hydraulic and electric actuators.
