Butterfly valves are used in a wide range of industrial applications to control the flow of liquids, gases, and slurries. The circular disc rotates on an axis to either allow or prevent flow through the pipe. Butterfly valves are valued for their simple operation, high reliability, low cost, and low pressure drop.
China is a leading global manufacturer of high-performance butterfly valves for industrial use. Chinese manufacturers utilize innovative butterfly valve designs and robust materials to create valves that outperform traditional designs.
Types Of Butterfly Valves Made In China
There are several main designs of butterfly valves produced by Chinese manufacturers:
The disc on a u-type butterfly valve is attached on the upper end of the pivot axis. The u-shape allows for unrestricted flow when the valve is open. This makes u-type designs well-suited for applications that require low pressure drop across the valve. They can handle high flow capacity while generating little turbulence.
A concentric butterfly valve has a pivot axis located at the center of the disc. This allows the disc to align perfectly with the flow when fully open yet still seal tightly when closed. Concentric discs provide optimal flow control and are easy to operate from fully closed to fully open.
Double eccentric butterfly valves have the pivot axis located above and offset from the center of the disc. When open, the disc seals against an elastomer gasket inside the pipe to create a bubble-tight shutoff. The offset pivot gives double eccentric valves the tight shutoff capabilities of eccentric valves with the high capacity of concentric types.
Advantages of Butterfly Valves from China
Butterfly valves from China offer several advantages over traditional designs:
- Advanced Disc Seals – Improved elastomer and metal disc seals prevent leakage even after thousands of open/close cycles.
- Durable Disc Materials – Discs made from stainless steel, cast iron, alloy steel, or other exotics resist corrosion, erosion, and high temperatures.
- Rangeability – Advanced disc profiles provide precise flow control over a wide range of flow rates.
- Low Torque Operation – Optimized bearings and seals reduce the torque required to operate the valve.
- Compact Size – Innovative designs allow substantial flow capacity through a compact valve body.
- Custom Configurations – Chinese factories can provide custom butterfly valves modified for specialized applications.
Ideal for Tough Industrial Applications
Thanks to their innovative features and robust construction, butterfly valves from China excel in harsh industrial environments, including:
- Chemical Processing – Corrosion-resistant exotic alloys handle volatile chemicals and acids.
- Slurry Transport – Heavy-duty seals withstand abrasive wear from slurries.
- Oil & Gas – High bidirectional shutoff protects against dangerous leaks.
- Power Generation – Precise flow control regulates steam, fuel oils, and combustion gases.
- Mining – Durable valves stand up to contaminated slurry flows and high differential pressures.
- Water Systems – Compact, high-capacity valves optimize municipal water distribution.
China butterfly valves outperform the competition in demanding industrial environments while providing substantial cost savings. With fast delivery times and responsive customer service, Chinese manufacturers make it easy to upgrade your piping systems with innovative butterfly valve technology. Evaluating Chinese suppliers on quality, testing, materials, and design is worthwhile to access butterfly valves engineered for optimal durability, performance, and safety.
