Step 1: Order and Design
According to customer requirements, the forged steel globe valve is confirmed in terms of size, pressure class, material, connection type, and applicable standards. Then technical drawings and production plans are prepared to ensure the valve structure and dimensions meet the project specifications.
Step 2: Forging & Casting
The main pressure-bearing parts of the forged steel globe valve, such as body, bonnet, and disc, are produced from high-quality forged steel materials. Forging improves the mechanical strength and internal density of the components, making the valve suitable for high-pressure and high-temperature working conditions.
Step 3: Machining
After forging, all valve components go through precision machining, including turning, drilling, threading, sealing surface machining, and flange finishing. This step is critical to ensure the forged steel globe valve has accurate dimensions, smooth sealing surfaces, and reliable shut-off performance.
Step 4: Assembly
All finished parts are carefully cleaned and assembled, including the body, bonnet, stem, disc, seat, gasket, and handwheel. During assembly, special attention is paid to sealing alignment and stem operation, so that the forged steel globe valve can open and close smoothly.
Step 5: Testing & Quality Assurance
Each forged steel globe valve is subjected to strict inspection and testing, such as shell pressure test, seat leakage test, dimension inspection, and visual examination. These procedures ensure the valve meets international standards and quality requirements before delivery.
Step 6: Painting and Finishing
After testing, the valve surface is cleaned, anti-rust treated, and coated if required. Finally, marking, packing, and final inspection are completed to ensure the product is ready for shipment in good condition.
Suitable for water, steam, oils, and corrosive media; operating temperature range: -29°C to 550°C.
