High-performance wafer butterfly valve is an industrial valve for precise flow control.
High-performance wafer butterfly valves are usually made of materials such as stainless steel, carbon steel or other corrosion-resistant alloys to ensure corrosion resistance and high temperature resistance.
The valve seat of high-performance butterfly valve is the biggest difference from ordinary double eccentric butterfly valve.
Bidirectional sealing: High-performance butterfly valves provide bidirectional sealing, which can effectively seal in both flow directions.
High-performance butterfly valves are the unique type which can be used for throttling.
CF3 stainless steel is the cast equivalent of 304L stainless steel, known for its corrosion and oxidation resistance. It performs well in mildly corrosive environments such as weak acids, chlorides and fresh water.
The polished surface can be used in systems such as drinking water.

What makes the seat design of high-performance butterfly valves unique?
The valve seat design is the defining feature distinguishing high-performance butterfly valves from standard double eccentric designs, enabling bidirectional sealing and suitability for severe flow control.
Can high-performance butterfly valves be used for throttling applications?
Yes, high-performance butterfly valves are unique valve types specifically capable of precise throttling and flow regulation in addition to standard isolation.
How does bidirectional sealing function in these valves?
These valves provide reliable bidirectional sealing, ensuring consistent shut-off performance regardless of the direction of fluid flow.
What are the characteristics and application environments of CF3 stainless steel?
CF3 stainless steel is the cast equivalent of 304L stainless steel, offering outstanding resistance to corrosion and oxidation. It performs optimally in mildly corrosive conditions including fresh water, chlorides, and weak acids.
Are these valves suitable for drinking water systems?
Yes, models manufactured with a polished surface finish are compliant and suitable for drinking water distribution networks.
What actuation methods are available for this valve?
The valve can be operated via Hand Lever, Gear Box, Electric Actuator, or Pneumatic Actuator, complying with standard ISO 5211 mounting interfaces.
