Industries
We Serve

Our butterfly valves are widely used for critical applications in the water treatment, chemical, petrochemical, oil and gas, power generation, mining and cryogenic industries.

Seawater Desalination

Butterfly valves are one of the mainstream valves in the seawater desalination field, and can solve pain points such as corrosion from high-salinity media, precise flow control in pretreatment and product water processes. High-performance hard-seal butterfly valves are used in high-pressure sections. These valves are available in duplex stainless steel, titanium alloy, and fluoropolymer-lined materials.

Water & Marine

Butterfly valves are highly adaptable and can cover three major scenarios in this field: municipal waterworks, sewage treatment, and shipbuilding and marine engineering. Large-diameter (DN500–DN3000) soft-seal centerline butterfly valves are core valves in water supply trunk lines and pumping stations. Fully lined butterfly valves are resistant to acids and alkalis in sewage. Marine-grade bronze or stainless steel butterfly valves are also available.

Oil & Gas

Butterfly valves meet stringent requirements such as fire prevention, anti-static properties, and zero leakage, making them suitable for complex operating conditions (high pressure, flammable, explosive, and sulfur-containing media) in the oil and gas industry.

Power Generation

Butterfly valves are widely used in thermal power, hydropower, and nuclear power plants. Thermal power plants use high-temperature hard-seal butterfly valves (withstanding temperatures above 450℃), hydropower plants use large-diameter eccentric butterfly valves, and nuclear-grade metal hard-seal butterfly valves for nuclear power plants must pass nuclear safety certifications such as RCC-M.

Learn More About Industries
Mining & Metals

Butterfly valves developed for the mining and metallurgical industries, particularly those with wear-resistant (including solid particulate media) and high-temperature (high-temperature smelting) properties, have received consistent praise from customers. Soft-seal eccentric butterfly valves, high-temperature butterfly valves, acid and alkali resistant butterfly valves, and large-diameter butterfly valves are commonly used in this field.
