This choice is critical for matching the valve to the fluid medium, temperature, and pressure requirements.
2. Casting/Forging:
   • Casting: For larger valve bodies, sand casting or investment casting is employed. Molten metal is poured into molds to form the valve body and bonnet. This method allows for complex internal geometries necessary for flow control. For cast iron globe valve flanged type, this is a common process.
   • Forging: Smaller, high-pressure valves often utilize forging. Metal is heated and shaped using compressive forces, enhancing grain structure and mechanical properties, leading to superior strength and fatigue resistance.
3. Heat Treatment: Components undergo specific heat treatment processes (e.g., annealing, normalizing, quenching, tempering) to optimize material properties such as hardness, strength, ductility, and machinability, reducing internal stresses.
4. CNC Machining: Precision Computer Numerical Control (CNC) machining is vital for achieving accurate flanged globe valve dimensions. This includes machining the flange faces, seat rings, stem, disc, and bonnet connections to tight tolerances. The seat and disc surfaces are critical for bubble-tight shut-off and modulated flow control.
5. Assembly: Components are meticulously assembled, including the stem, disc, packing, gland, and handwheel. Proper alignment and lubrication are crucial for smooth operation.
6. Testing and Inspection: This is a critical phase ensuring quality and compliance.
   • Hydrostatic Shell Test: Performed to confirm the valve body's structural integrity and ability to withstand design pressure without leakage, typically to standards like ISO 5208 or ANSI/API 598.
   • Seat Leakage Test: Verifies the sealing capability of the disc and seat, ensuring minimal or zero leakage in the closed position.
   • Functional Testing: Checks stem operation, packing integrity, and overall valve movement.
   • Non-Destructive Testing (NDT): For critical applications, methods like radiographic testing, ultrasonic testing, magnetic particle inspection, or dye penetrant testing may be used to detect internal flaws.
7. Surface Treatment and Finishing: Painting, coating, or passivation is applied to enhance corrosion resistance and appearance, especially for valves exposed to harsh environments.

Adherence to standards like ISO, ANSI, API, and DIN (e.g., DIN 3202-F1 for face-to-face dimensions) throughout this process guarantees a service life of 15-25 years or more under normal operating conditions. These valves are designed to offer energy saving benefits through precise flow regulation and corrosion resistance tailored to the application.
