API Cast Flange Globe Valve
This product is a API Cast flange globe valve, designed for precise flow regulation and shutoff in industrial pipeline systems. The body is made from high-strength cast materials, providing excellent pressure resistance and stable performance for long-term operation in oil, chemical, power, and general industrial media applications.
The valve disc, with a wedge or flat design, allows accurate flow control and ensures tight sealing to prevent leakage. The rising stem provides a clear visual indication of valve position, facilitating on-site operation and monitoring. Flanged ends feature ANSI RF (Raised Face) sealing surfaces, ensuring easy installation and reliable sealing, fully compatible with standard pipeline systems. Manual operation offers simple and flexible control with minimal maintenance requirements. This globe valve is widely used in industrial pipelines as an effective solution for flow control and fluid isolation.

Structural Characteristics of
The valve body is manufactured from CF8 austenitic stainless steel, offering excellent corrosion resistance and mechanical strength, suitable for both corrosive and non-corrosive media, in compliance with ANSI / ASTM standards.
The straight-through globe valve design allows the disc to move linearly along the seat centerline, providing reliable shut-off and precise flow regulation.
ANSI standard flanged ends with raised face (RF) ensure secure connection, easy installation, and convenient maintenance in pipeline systems.
Handwheel-operated design provides smooth opening and closing, ideal for applications requiring frequent operation or reliable shut-off.
Precisely machined disc and seat surfaces minimize wear caused by flow erosion, ensuring tight sealing and extended service life.
Suitable for water, steam, oil, gas, and chemical media, widely used in chemical processing, petroleum, pharmaceutical, power generation, and general industrial systems.
