I. Product Introduction
The Pneumatic Hard-Sealed Flanged Butterfly Valve (Model: D643Y) is an automated fluid control device driven by a pneumatic actuator, featuring a hard-sealed structural design. Its sealing surface undergoes professional hardening treatment, and it adopts a flanged connection method, which ensures excellent sealing performance and structural stability.
Designed specifically to adapt to harsh industrial working environments (such as high temperature, high pressure, abrasion resistance, or strong corrosion), this valve can realize the opening, closing, and regulation of media in fluid systems. It is widely used in pipeline systems of petroleum, chemical, electric power and other fields.
II. Product Features
- Hard-Sealed Structure: The sealing surface is hardened, providing excellent wear resistance and corrosion resistance, enabling long-term stable operation under severe working conditions.
- Pneumatic Actuation: Equipped with a pneumatic actuator, it features fast response speed and facilitates remote automatic control, improving operational efficiency.
- Flanged Connection: Adopting standard flanged connection, it is easy to install, with good sealing performance and high reliability.
- Excellent Flow Performance: The butterfly valve structure offers optimal flow characteristics and low flow resistance loss, helping to improve the conveying efficiency of the pipeline system.
- Stable Structure: The overall structure is compact with reasonable mechanical properties, resulting in low vibration and high stability during operation.
