The core application scenario for angular stroke electric actuators lies in operating conditions requiring rotational movement of valves or baffles, with a standard rotation angle of 90° (certain specialized models support multi-turn rotation). These actuators are engineered for specific compatibility with distinct valve types and industrial operating environments.
Angular stroke electric actuators are primarily paired with rotary valves, which regulate media flow or on-off status via the rotation of valve discs or valve cores. Common compatible valve types include:
-
Ball Valves
The spherical valve core enables full opening or closing with a 90° rotation. Widely utilized for media isolation, diversion, and throttling in chemical, petroleum, and water treatment sectors.
Typical applications: Ball valves for natural gas transmission pipelines; blowdown ball valves in water treatment systems.
-
Butterfly Valves
Featuring a disc-shaped valve core that achieves open/close status through a 90° rotation, these valves are characterized by a compact structure and high flow capacity. Ideal for large-diameter, low-pressure differential operating conditions.
Typical applications: Large-diameter butterfly valves in municipal water supply and drainage networks; flue butterfly valves in power plant flue gas desulfurization systems.
-
Plug Valves
The conical or cylindrical valve core adjusts flow passage cross-sectional area via rotation, making it suitable for high-pressure and high-temperature media control scenarios.
Typical applications: High-pressure plug valves in oil extraction operations; control plug valves for steam pipelines.
-
Air Dampers/Baffles
Designed for air volume or flue gas volume regulation in air ducts and flues, with baffle rotation driven by the actuator to adjust opening degree precisely.
Typical applications: Air intake baffles in boiler combustion systems; flue gas baffles at cement kiln tail ends.
Tailored to the sectors you focus on—including petroleum, water treatment, wind power, and marine vessels—specific application scenarios are detailed below:
-
Petrochemical Industry
Applications cover ball valve control in crude oil transmission pipelines, reflux control valves (butterfly valves) in refinery distillation columns, and inlet/outlet isolation valves for storage tanks. These scenarios demand resistance to high-temperature, high-pressure, flammable, and explosive media environments. Angular stroke actuators can be configured with explosion-proof designs to meet such stringent requirements.
-
Water Treatment Industry
Used for outlet butterfly valves in waterworks sedimentation tanks, sludge discharge ball valves in wastewater treatment plants, and flow control butterfly valves in industrial circulating water systems. These actuators are optimized for large-diameter, low-pressure operating conditions and ensure stable proportional regulation performance.
-
Wind Power Industry
Applied in control valves (plug valves) within wind turbine hydraulic systems and baffle regulation for nacelle heat dissipation air ducts. These applications require reliable operation in harsh outdoor environments with low temperatures and high altitudes. Angular stroke actuators with a protection class of IP67 or higher are fully compatible with such conditions.
-
Marine Vessel Industry
Deployed in fuel supply ball valves for ship power systems, butterfly valve control in ballast water systems, and bilge water discharge valves. Components must exhibit corrosion resistance (for seawater exposure) and vibration resistance. The compact footprint of angular stroke actuators also makes them well-suited for the limited installation space on board vessels.
