Features：
● The sealing characteristics is similar to flanged diaphragm valve, large flow.
● The valve body can be removed from the pipe line by loosening the union nuts at both its ends.
● Existing cases show that due to factors such as installation errors in factory pipelines, it is easy to cause the union nut to be overstressed and leak or even be damaged. Therefore, it is not recommended to use a valve with a union connection structure above DN50.

Steam pipeline systems are widely used across power generation, chemical processing, metallurgy, and paper manufacturing industries. When operating parameters enter the high-temperature, high-pressure range — particularly supercritical steam service above 374°C and 22.1 MPa, or subcritical steam sys...
In the field of industrial valve engineering, the internal support mechanism of a manual ball valve fundamentally determines its applicable pressure range, operational torque characteristics, and long-term sealing reliability. The two dominant designs — floating ball and trunnion-mounted ball — diff...
PPH (Polypropylene Homopolymer) pipes are widely used in industries such as chemical processing, food production, pharmaceuticals, and water treatment due to their excellent corrosion resistance, high-temperature tolerance, and overall durability. However, the performance of a PPH piping system heav...
PPH (Polypropylene Homopolymer) pipes are widely recognized for their excellent corrosion resistance, high-temperature tolerance, and long service life. These properties make them ideal for various industrial applications, including fire protection systems. In this article, we will discuss the appli...
The Engineering Logic Behind Butterfly Valve Selection The butterfly valve has established itself as a cornerstone of modern fluid control due to its simple yet effective design. Its primary mechanism involves a circular disc—positioned in the center of the pipe—that rotates on a shaft. A 90-degree ...
Automatic Butterfly Valve Overview In the field of industrial fluid control, the cost of an Electric Actuated Butterfly Valve is not a simple figure but a complex variable influenced by multiple technical specifications. Understanding these cost components not only helps in optimizing budgets but al...
