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.
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
Bronze Flanged Gate Valve plays a vital role in the pipeline system, and its core role is mainly reflected in the following aspects:
Copper-based alloys bronze and brass have their own characteristics in performance and application areas, and users need to weigh their differences when selecting.
Bronze is an alloy of copper and tin, and may also contain other elements. It is widely used in valve manufacturing, mainly due to its excellent corrosion resistance and high strength. The design of the check valve is to prevent the backflow of the medium, which requires it to have the characteristics of automatic closing and low resistance in the structure.
Bronze butterfly valves have many remarkable characteristics, including excellent materials, good corrosion resistance and high temperature resistance, simple structural design and light weight, which make them excellent in low-pressure sealing and easy to operate. In particular, the aluminum bronze butterfly valve, with its outstanding corrosion and wear resistance, is very suitable for seawater and corrosive media environments, with a simplified structure, low fluid resistance and extremely low leakage rate.
From the material point of view, bronze and brass differ in alloy composition. Bronze is made of copper-tin alloy with a copper content of more than 60%. Brass is a copper-zinc alloy with a copper content of less than 60%. Bronze also contains elements such as tin and lead, while brass uses zinc as the main added element, so the material composition constitutes the basic difference between the two.
On the sunny winter day of December 5, 2024, our entire company converged at a charming estate in Liandu District, Lishui City, for an exhilarating team building event.
A backseat is a sealing mechanism which can prevent medium leaking into the packing material when the valve is fully open.
PTFE (Polytetrafluoroethylene):Known for its high chemical resistance and low friction, PTFE is a widely used material for ball valve seals. Its ability to resist a broad spectrum of chemicals makes it ideal for corrosive environments. Additionally, PTFE’s low friction properties contribute to smoother operation and reduced wear over time.
The Quick Opening Cover With Davit Arm Strainer is an enhanced version of the traditional basket strainer. Compared with the traditional basket strainer, the most prominent feature is the Davit Assembly, which is used to support and fix the Quick Opening Cover and Davit Arm Strainer.
In order to ensure quality control and improve product quality and safety, we Sedelon have established a complete valve traceability system mainly through the following aspects.
