◆ Electric actuators are mainly used in power plants or nuclear power plants, because the high-pressure water system requires a smooth, stable and slow process. The main advantages of electric actuators are high stability and constant thrust that users can apply. The anti-deviation ability of the electric actuator is very good, and the output thrust or torque is basically constant, which can well overcome the unbalanced force of the medium and achieve accurate control of the process parameters, so the control accuracy is more than that of the pneumatic actuator high.

Electric actuators are mainly used in the following three areas

◆ Power plant

Typical applications are:

① Application in thermal power industry

Air blower damper primary air inlet damper air preheat damper flue gas recirculation bypass damper secondary air inlet damper main wind box damper damper burner adjustment lever burner swing drive hydraulic push rod drive impeller Machine speed control flue gas control valve steam control valve ball valve and butterfly valve control sliding gate gate

②Valve actuator applications in other power industries

Ball valve dust control water jet impeller speed control control large hydraulic valve gas control valve burner ignition start steam control valve condensate recirculation, deaerator, boiler feed water, superheat controller, reheat thermostat controller, and other related valve applications

◆ Process control

Used in the production process control of chemical, petrochemical, mold, food, medicine, packaging and other industries, according to established logic instructions or computer programs to accurately position, start and stop valves, tools, pipelines, baffles, chutes, platforms, etc. , Opening and closing, rotation, using the temperature, pressure, flow, size, radiation, brightness, chromaticity, roughness, density and other real-time parameters detected by the system to adjust the system, so as to realize the control of intermittent, continuous and cyclic processing .

◆ Industrial automation

It is used in a wide range of aviation, aerospace, military, machinery, metallurgy, mining, transportation, building materials, etc., to adjust and control the movement points (moving parts) of various automation equipment and systems.

Examples of main applications in process control and industrial automation are as follows:

① Application in the production of sulphur ore

Water injection flow control ball valve and butterfly valve control

②Application of Potassium Carbonate Pipeline Valve Actuator

Sliding gate diverter Gate ball valve and butterfly valve Ball control valve

③Application of water treatment valve actuator

Liquid flow control, pressure regulator pressure control, acid solution flow control

④ Application of valve actuators in limestone/cement plants

The ball or butterfly valve controls the treatment of dry cement, gypsum, or liquid. The air supply and the induced draft fan adjust the damper damper. Bypass damper damper. Environmental pollution control and dust removal device. Sliding door controls the logistics of raw materials in the hopper and storage. The gate controls the raw materials in The gas control valve at the feed port adjusts the intake air volume of the burner on the converter. The steam control valve controls the steam required for the production process.

⑤Application of actuators in grain processing plants

Gate Diverter valve Distributor Material unloader/heater Dust removal isolation baffle Air flow control (logistics drying) Ball valve and butterfly valve control

⑥Application of damper and valve actuator in steel mill

Ball or butterfly valve controls the control of cooling water, waste water, or other cooling media. Adjustable damper baffle air supply and induced draft fan bypass damper damper gate Environmental pollution control and dust removal device Sliding door controls the flow of raw materials at the inlet to the hopper and The raw materials in the storage warehouse are subject to logistics control, gas control valve, steam control valve, adjustment of the burner on the converter, and control of the steam required for the production process

⑦Application of damper and valve actuator in aluminum factory

⑧Application of process control baffle

Air replenishment Exhaust fan bypass Hot/cold air mixing Emergency shutdown

⑨Application in petroleum industry

Oil injection process flow control Gas lift pipeline main valve pressure control Water injection process flow control Oil well oil quality sampling test / production valve

⑩Application in natural gas production and transportation industry

Gas lift airflow flow control Gas pipeline main valve pressure control Compressor surge control Natural gas pressure control Natural gas pipeline main valve pressure control Emergency shutdown Natural gas pressure regulator control Pressure control Compressor surge control Flow control
