With over 25 years of industry experience, we deliver engineering excellence, ensuring every quarter-turn gear solution meets the rigorous demands of global fluid control markets.
Stard-gears is a leading global provider specializing in valve control technology. Application scenarios for our products include oil, chemical, natural gas, nuclear, and water treatment systems.
We are committed to product innovation, quality and reliable solutions to help our customers better manage their valves under extreme pressures and corrosive environments.
We are from Suzhou, China. The Yangtze River Delta region of China has a well-established and convenient industrial supply chain, which ensures that our castings, advanced machining capabilities, and spare parts procurement are advantageous at the same time.
This allows us to seamlessly meet both fast delivery schedules and superior product quality requirements for international EPC contractors.
Stard-gears is a modern company integrating research & development, production, sales and trade, aiming firmly at becoming the definitive global industry leader.
Based on our mission statement of “excellent reputation, best quality and perfect service”, we continuously strive to serve fluid control clients worldwide.
Over the last 10 years, our robust quarter-turn gearboxes and valve operators have been extensively exported to the United States, Italy, Germany, Mexico, Singapore, Japan and numerous other industrial economies.
Stard offers 9 distinct series and about 80 varieties of gear operators, providing tailored solutions for diverse pipeline configurations.
Through 3D simulation, dynamic simulation, finite element analysis (FEA), etc., our senior mechanical engineers can virtually verify the structural rationality of every new product design before physical prototyping.
This advanced engineering workflow significantly shortens the R&D cycle, guarantees the ultimate safety and torsional endurance of final products, and minimizes customer investment costs.

Stard Automation runs a comprehensive ERP management system to ensure that the production schedule and real-time progress of each client order are transparent and tracked.
Real-time supervision is implemented across all manufacturing stages to maximize operational efficiency and eliminate bottlenecks.
The annual output value of our Suzhou advanced manufacturing plant reaches $9,000,000, with an impressive annual production volume peaking at 100,000 sets of high-precision gear operators.
We maintain massive inventory of blank castings and core components to guarantee rapid order fulfillment.
To ensure flawless performance, Stard Automation has established dedicated full-time QC inspection stations at every critical manufacturing stage — from incoming raw casting materials and in-process machining control to final assembly and packaging.
We guarantee that 100% of our gear operators are fully qualified before dispatching to global job sites.
Our facility owns a comprehensive suite of advanced inspection and testing equipment designed to monitor quality parameters from blank casting to finished gearbox.
This high-tech infrastructure empowers us to perform rigorous industrial evaluations including torque output tests, waterproof immersion tests, and long-term mechanical life cycle tests.
Suzhou, located in the Yangtze River Delta, benefits from a mature industrial cluster offering superior raw material castings, advanced CNC machining ecosystems, and highly skilled engineering talent. This translates to cost-effective pricing ("cheap" without compromising quality), shorter lead times, and rigorous international quality compliance.
Quarter-turn gearboxes are essential for operating 90-degree rotational valves such as butterfly, ball, and plug valves. They are widely utilized across demanding sectors including oil & gas pipelines, chemical processing plants, municipal water treatment systems, power generation, and nuclear facilities.
We adhere strictly to ISO9001 quality management systems. Every unit undergoes rigorous 100% testing including finite element structural verification, torque capacity tests, and mechanical life cycle evaluations prior to global shipment, backed by CE and relevant industrial certifications.
