Ball valves are among the most widely used flow-control components across industrial piping systems. Their robust structure, reliable sealing performance, and quick quarter-turn operation make them indispensable for oil & gas, chemical processing, power plants, water treatment, HVAC, and high-pressure applications.
At Mecco, our commitment to precision engineering is backed by 500+ sets of advanced CNC machines, forging lines, welding systems, pressure-testing rigs, and automated inspection equipment—allowing us to deliver world-class full port ball valves, high pressure ball valves, reduced port ball valves, and specialized designs such as vented ball valves.
This article explains the complete ball valve manufacturing process, from raw materials to final testing, while showcasing the production strengths that set Mecco apart as a trusted global valve manufacturer.

High-quality stainless steel is widely used for ball valve manufacturing due to its excellent corrosion resistance, durability, and mechanical strength. Depending on pressure class and medium, materials may include:
For demanding industries, Mecco uses a forged ball valve structure to ensure higher density, improved toughness, and superior resistance to high pressure and temperature.
Forging is the first major step in the ball valve manufacturing process. It enhances metal strength by eliminating internal voids and improving grain structure.
Mecco operates multiple automated forging lines that shape valve bodies with precision dies. This ensures:
Forged bodies are essential for high pressure ball valves used in demanding service conditions.
Mecco’s manufacturing leadership stems from its investment in more than 500 sets of CNC machining centers, including:
This allows perfect machining of:
With this technological advantage, valve dimensions, tolerances, and sealing surfaces remain extremely consistent.
The ball is the heart of every ball valve. Its performance directly influences flow control, sealing capability, and operating torque.
A smooth ball surface ensures excellent sealing in both open and closed positions, minimizing friction and extending valve life.
The ball rotates inside the valve body through a quarter turn to open or close the flow path. Proper assembly is critical for ensuring long-term reliability.
Mecco’s assembly lines incorporate:
Each valve is assembled to guarantee:
Every valve undergoes strict valve testing before shipment. Mecco’s testing facilities include:
All ball valves—whether full port, reduced port, manually operated, or high pressure designs—are tested according to API, ISO, and EN standards.
Testing ensures long-term dependability, safety, and compliance for global industries.
Ensures high-precision machining, forging, and testing capabilities.
Guarantees consistent quality across the entire production chain.
Ideal for extreme industries requiring maximum durability and corrosion resistance.
Trusted by global valve distributors and end-users.
Full port, reduced port, vented ball, quarter-turn valves, high-pressure trunnion, floating designs, and more.
A full port (full bore) ball valve has a ball opening equal to the pipe diameter, allowing maximum flow.
A reduced port valve has a smaller opening, offering more controlled flow but slightly higher pressure loss.
Forging eliminates internal voids, increases strength, and ensures structural reliability—making forged ball valves ideal for high pressure applications.
A ball valve uses a quarter-turn rotation. When the ball hole aligns with the flow, the valve is open. When rotated to the closed position, the flow is completely blocked.
Stainless steel, carbon steel, duplex stainless steel, and special alloys, depending on corrosion resistance and pressure requirements.
A vented ball includes a small vent hole that prevents pressure buildup when the valve is closed, improving safety in certain applications.
Through forging, CNC precision machining, clean assembly, and rigorous final pressure testing, all done using over 500 advanced machines.
The ball valve manufacturing process involves advanced material selection, forging, CNC machining, precision assembly, and strict pressure testing. With 500+ sets of specialized manufacturing and testing equipment, Mecco delivers consistent quality, superior durability, and high-performance ball valves for global markets.
Whether you require full port, reduced port, forged, or high-pressure ball valves, Mecco’s vertically integrated production ensures unmatched reliability and professional authority.
