Cast Steel Globe Valve is a common pipeline control device primarily used to block or allow the flow of medium in pipelines. This type of valve achieves on/off functionality by moving the valve disc up and down along the centerline of the valve seat via the valve stem. It features simple structure, excellent sealing performance, and easy maintenance.

Structural Features
Rational Design
The cast steel globe valve series features a rationally designed structure, ensuring stable performance, reliable quality, easy installation, and lightweight and flexible operation.
Reliable Sealing
The sealing surfaces of the valve disc and seat are hardfaced with hard alloys of varying hardness, providing reliable sealing, high hardness, excellent wear resistance, high-temperature resistance, and anti-scoring performance, with a long service life. Some product sealing surfaces are further enhanced with Co-based hardfacing alloys, significantly improving wear resistance, corrosion resistance, and anti-scoring performance.
Durable Valve Stem
The valve stem undergoes heat treatment, tempering, and surface nitriding, offering good anti-scoring and wear resistance.
Versatile Connection Types
Cast steel globe valves support multiple connection methods, including national standard flange connections, socket welding connections, butt welding connections, and threaded connections. This adaptability meets various piping requirements, flange standards, flange sealing surface types, and diverse engineering needs and user specifications.
