The main products of this company are Bronze valves, API/DIN gate/globe/ check valves/butterfly valve/plug valve, ball valves and forged steel valves. Its products have been widely used in petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, machinery and many other fields.
In modern industrial systems, environmental protection and safety have become important issues that cannot be ignored. Fugitive emission gate valves play a vital role as key devices for controlling the release of harmful gases or liquids. These valves effectively prevent the leakage of pollutants and ensure the tightness and reliability of the system by adopting advanced sealing technologies such as double seal design and metal-to-metal contact.
Flange gate valves are a vital control device in pipeline systems, and their main function is to control the flow of fluids. It opens or closes the flow channel by lifting or lowering the built-in gate, thereby achieving precise control of fluid flow. This valve is particularly popular because of its simple and efficient design, providing minimal flow resistance, especially when fully open.
Flanged End Forged Gate Valve plays a key role in high-pressure pipeline systems. As a solid guardian, it is mainly used to regulate fluid flow, especially in high-pressure and high-temperature applications. The valve is made of forged steel material, and its structural strength and toughness are enhanced by high-temperature forging process, so that it can withstand extreme pressure and temperature changes, ensuring stable operation under harsh conditions.
In modern industry, pipeline fluid control equipment is essential. The DIN 3352 Gate Valve is a high-quality valve designed specifically for this purpose. It meets the standards of the German Institute for Standardization (DIN), ensuring its consistency and reliability in the global market.
As a key control element of the pipeline system, cast steel gate valves are of irreplaceable importance in the field of fluid regulation. This valve device, cast from special steel, exhibits excellent performance under various harsh working conditions due to its unique material properties and structural design.
Due to its high carbon content (≤2.11%) and optimized alloy composition, carbon steel materials give gate valves excellent mechanical strength and impact resistance. Under high pressure conditions, the carbon steel valve body can withstand pressure levels exceeding Class 1500, and under high temperature environments (≤560℃), its anti-creep properties effectively prevent valve deformation and ensure long-term sealing stability.
API 602 Forged Gate Valve is a high-performance valve designed for regulating fluid flow in high-pressure and high-temperature industrial systems. These valves are manufactured in accordance with the American Petroleum Institute (API) 602 standard and are made of forged steel, ensuring their strength, durability, and resistance to corrosion and wear.
The design and manufacturing follow the American National Standard ANSI B16.34 and the Petroleum Institute Standard API600, which is suitable for high temperature and high pressure conditions. The wedge-type single gate structure (elastic or rigid) is adopted to ensure reliable sealing and avoid gate wedging.
Bronze valves are made of copper and are alloyed by adding tin, aluminum and other elements. This alloy has high mechanical strength and hardness and can withstand high pressure conditions, such as ship fuel systems and chemical pipelines. The grain structure of the bronze alloy has been optimized. For example, phosphorus can refine the grains, which significantly improves the service life of the valve in frequent opening and closing or vibration environments.
Bronze Strainer Valve achieves effective interception of impurities in the fluid and precise regulation of flow through the synergy of filtering structure and valve control. Its core mechanisms mainly include the following aspects:
The differences between Bronze Globe Valve and cast iron globe valve in appearance are mainly reflected in color, surface texture and weight density.
The leakage level of bronze gate valves is usually classified according to the provisions of API 598 [4]. This classification mainly distinguishes different leakage levels based on the size of the leakage, and sets different leakage levels according to the different media used. At the same time, the leakage level can be further divided into multiple categories, such as
