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.

Belleville disc springs
 
provide live loading to ensure a tight top seal.
 
Blow-out proof design
 
Stem and disc are one simple part combined with the anti-blow-out system. (API 609 compliant.)
 
The extended body lining
 
assures optimum protection of the PTFE-rings from corrosive media.These components are located behind the body liner extension. They are
 
isolated from the media.
 
The revolutionary PTFE atmosphere seal
 
protects the top seal components and the shaft from atmospheric corrosion.
 
Triple PTFE-ring backup-seals
 
provide a second, third and fourth line of protection against atmospheric leakage.
 
The in-line resilient seal assembly
 
assures optimum pressure distribution of the body liner to the disc assembly, providing tight sealing under all operating conditions. The wider seal-
 
band provides a broader sealing area.
Fully lined bottom shaft
 
assures optimum corrosion resistance and eliminates a potential leakage path.
