Metallurgy is the process of removing impurities (unintended elements) from molten metal by creating and separating slag through melting (heating above the melting point). At the same time, certain chemical components are refined to achieve a relatively pure alloy composition through processes such as slag removal, decarburization, and deoxidation.

The chemical industry plays a vital role in the national economy of countries worldwide, serving as a foundational and pillar industry for many nations. Its pace of development and scale have a direct impact on various sectors of the socioeconomic system. Permeating nearly every aspect of modern life, the chemical industry is an indispensable component of the national economy. Advancing along a sustainable development path holds significant practical importance for both human economic and social progress.

For the chemical industry, our company supplies a comprehensive range of valves, including ball valves, gate valves, float ball valves, check valves, and more, designed to meet diverse operating conditions and application requirements.

A ship is a primarily waterborne human-made vehicle. In general, civilian vessels are referred to as "ships," military vessels as "warships," and smaller craft as "boats" or "dinghies," collectively termed as vessels or watercraft. Their structure mainly comprises enclosed spaces, supporting frameworks, and water-displacing hulls, equipped with propulsion systems that utilize external or onboard energy sources.

The objective of the water conservancy industry is to comprehensively plan and rationally arrange the control, development, and utilization of surface water and groundwater resources, striving to achieve maximum safety, economy, and efficiency.

Purification is achieved by either adsorption or barrier methods to remove impurities from water. A key adsorption method utilizes activated carbon, while barrier methods involve passing water through filter media to block larger impurities, thereby obtaining cleaner water.

In water treatment plants, large butterfly valves and gate valves are used in pumping stations and water supply networks.

These facilities manage the flow of wastewater, sludge, and liquid chemicals (such as coagulants). Commonly used valves include knife gate valves (suitable for media containing solid particles), butterfly valves, and ball valves.

In the oil and gas industry, valves are essential equipment for the safe operation, maintenance, retrofitting, and development of oil and gas transmission, distribution, and storage systems. They are widely used across various installations, including onshore production facilities, offshore production platforms, oil and gas separation units, compressor stations, gas processing plants, distribution stations, urban pipeline networks, refineries, petrochemical plants, storage terminals, and fueling stations.

Within the industry, valves serve critical functions in internal gathering and transmission networks of oil and gas fields, natural gas purification and processing plants, transportation of crude oil, refined products, and gases, compressor stations, crude oil storage terminals, natural gas storage facilities, offshore platforms, subsea pipelines, urban distribution networks, and well water injection systems, including emergency shutdown applications.

Given that oil and gas are highly flammable and explosive substances, ensuring the safe and reliable operation of valves throughout their service life is of paramount importance.

Electricity is primarily generated through the following means: thermal power (using combustible materials such as coal), solar power, large‑capacity wind power technology, nuclear power, hydrogen power, and hydropower.

In the power industry, valves serve as critical components of fluid control systems. They not only regulate the flow of media but also ensure the safe, stable, and efficient operation of the entire system.
