Step 1: Order and Design
Confirm customer requirements, including size, pressure rating, material, end connection, and applicable standards.
For the forged steel ball valve, technical drawings and production plans are prepared before manufacturing starts.
Step 2: Forging & Casting
The main body and key pressure-containing parts are produced by forging to ensure higher strength and better internal structure.
For a forged steel ball valve, forged raw material is selected, heated, and formed, then rough cleaned for the next process.
Step 3: Machining
All forged parts are machined by CNC equipment, including body cavity, flange ends, stem hole, ball, and seat pocket.
This step is critical for the forged steel ball valve to ensure dimensional accuracy, sealing performance, and smooth operation.
Step 4: Assembly
After machining and inspection, all components are assembled, including body, ball, stem, seat, gasket, bolts, and handle.
Each forged steel ball valve is assembled according to standard procedures to guarantee reliable performance.
Step 5: Testing & Quality Assurance
Finished valves undergo pressure test, shell test, seat leakage test, and operation test according to international standards.
Every forged steel ball valve must pass quality inspection before delivery.
Step 6: Painting and Finishing
After testing, the valve surface is cleaned, painted or anti-rust coated, marked, packed, and prepared for shipment.
