S Nomi is a leading Globe Valves Manufacturer providing high-quality valve solutions to industries across Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam. Our globe valves are designed for optimal performance and durability, making them ideal for various industrial applications requiring precise flow control.

What are Globe Valves?

A Globe Valve is a type of valve used to regulate the flow of liquids or gases by moving a disc or plug perpendicular to the flow direction. Unlike gate valves, globe valves are specifically designed for throttling or regulating flow, offering a more controlled and precise operation. The name “globe valve” comes from the shape of the valve body, which resembles a globe.

Manufacturing Details of Globe Valves

At S Nomi, our manufacturing process ensures that each globe valve meets stringent quality and performance standards:

1. Material Selection: We use high-grade materials such as stainless steel, carbon steel, cast iron, and bronze, depending on the specific application. These materials ensure corrosion resistance and durability, especially in challenging environments.
2. Casting and Forging:
   • Casting: The body of the globe valve is typically made using precision casting methods, ensuring accurate dimensions and robust construction.
   • Forging: The stem, bonnet, and other high-stress components are often forged for added strength.
3. Machining: CNC machines are used to machine critical parts of the valve to ensure high precision and smooth operation. This includes the valve disc, seat, and stem, which need to maintain close tolerances for effective flow control.
4. Assembly: Each component, including the body, seat, disc, stem, and bonnet, is carefully assembled to ensure smooth functionality. Special attention is given to the sealing surfaces to prevent leakage.
5. Testing and Quality Control:
   • Hydrostatic Testing: Globe valves are subjected to rigorous hydrostatic pressure tests to ensure leak-proof operation under high pressure.
   • Pneumatic Testing: Valves are also tested with air pressure to check for potential leaks in low-pressure systems.
   • Non-Destructive Testing: Techniques like ultrasonic testing and radiography are used to detect internal flaws in the valve components.
6. Surface Treatment: Depending on the application, the valves may undergo surface treatments such as galvanization, painting, or polishing to enhance corrosion resistance.
7. Inspection and Packaging: After final inspection, the valves are packed securely to ensure safe transportation.
