Sun Yeh Electrical Ind. Co. Ltd. was established in 1986 to respond to customer demands and expectations. Based on this principle, OM series quarter turn electric control valve actuator, spring return fail-safe series valve actuator, and linear series electric actuators were developed.
Sun Yeh electric actuators fit with various types of valves such as butterfly valves, ball valves, plug valves, dampers, and globe valves, which are widely applied in industrial technology, irrigation, water treatment, HVAC, chemicals, food processing, mining, tunnel/metro ventilation, smoke extraction, the food industry, and environmental protection systems.
An advanced quality management system is essential to achieve such superior quality products. Hence we have been strictly controlling our quality over the years with advanced technology and instrumentation. Each actuator is inspected and calibrated before shipment. Sun Yeh products are certified in accordance with CE, CSA, ATEX, IECEx, and SIL certification, in addition to ISO 9001 quality certification.
