Features：
● Sealing performance has been improved due to its specially designed seat.
● Thickened valve body and reinforcing ribs, no hollow design, design optimization for stress concentration, enhance the strength of the valve under harsh conditions
● Spherical design disc provides superior durability and improved Cv value.
● Optional cast iron (default), plastic or aluminum alloy worm gear box.

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...
