Sun Yeh Electrical Ind. Co., Ltd.

OIL & GAS

The oil and gas industries commonly utilize actuators for controlling the flow and regulation of gases, liquids, and crude oil. Sun Yeh specializes in manufacturing electric actuators, offering a range of options for customers.

WATER INDUSTRY

Sun Yeh offers robust quarter-turn electric actuators (OM, CM, S series) with corrosion-resistant coating NEMA 4X enclosure, and multi-turn actuators (M series) with IP68 enclosures that are durable and can be used in open/close valve applications to divert flow to respond to the treatment requirements and in modulating applications to control the flow to adjust the amount of medium passing through the valve into or out of the treatment plants.

ENERGY

Our electric valve actuators can be used as nuclear valves, pollution control valves, feeding water valves, cooling water valves, chemical treatment, and steam turbine control systems valves. We offer electric valve actuators (OM, S, L, and M series) to withstand the harsh environments of the power industry for use in ventilation systems, cooling systems, fluid control, etc., in power plants.

CHILLER & COOLING TOWER / HVAC

Sun Yeh offers advanced cooling valve actuators designed specifically for chillers and cooling towers applications, as well as HVAC actuators for thermal cycle management. Our quarter-turn (OM, T, CM series) and linear actuators (L series) are ideal for use in various industries, including refineries, sugar industry, distilleries, chemical industries, pharmaceutical industries, food and beverage, paper mills, shipbuilding, refrigeration, air conditioning, plumbing, and heating equipment.

TUNNEL / METRO

Sun Yeh offers fire and smoke damper actuators that are applicable for normal operation such as temperature, humidity, and indoor air quality controls or smoke extraction in case of fire to ensure the safety and comfortability of the environment in tunnels and stations.

Agriculture & Animal Husbandry

Sun Yeh electric valve actuators can be used in agriculture, by the use of various actuated control valves to regulate the flow of water to reduce water waste. Our quarter-turn valve actuators (OM, CM series) are suitable for ball valves or butterfly valves to be installed outdoors in the application of agricultural irrigation and animal husbandry. Additionally, OM quarter-turn actuators allow operating the valves by manual override when there is a power failure for continuous operation without hindrance.

DATACENTER COOLING & INFRASTRUCTURE

As global data consumption continues to surge, datacenters are evolving into high-density, high-performance hubs. This transformation demands precise environmental control to ensure system stability, energy efficiency, and uninterrupted operation.

SEMICONDUCTOR MANUFACTURING PROCESS

Semiconductor fabrication requires ultra-clean, tightly controlled environments. As process nodes shrink and yield targets rise, precision in fluid and airflow control becomes mission-critical.
