GB Manual Flange Ball Valve

The GB Manual Flange Ball Valve is a robust industrial valve designed for applications requiring reliable shut-off in pipelines. It conforms to GB standards and is available in sizes ranging from DN15 to DN100, with a pressure rating of PN16. The valve body is constructed from CF8 (ASTM A351), a stainless steel grade offering nice corrosion resistance, making it suitable for water, oil, gas, and mild chemical services.

This valve features a flanged connection for easy installation and maintenance, ensuring a secure fit with standard pipeline flanges. The manual lever operation provides precise control over fluid flow, while the full-bore design minimizes pressure drop. The ball valve is designed for durability, with a PTFE seat ensuring tight sealing and smooth operation over extended periods.

Its applications include industrial processing, water treatment, and general-purpose fluid control systems where corrosion resistance and leak-proof performance are essential. The GB-standard design ensures compatibility with pipelines in regions adhering to metric system specifications.
