What are the main uses of electric actuators?

Date:Jan 02, 2019

At present, the layout of the valve market is mainly based on the construction of engineering projects. The main users of valves are petrochemical industry, power industry, metallurgical industry, chemical industry and urban construction industry. Electric actuator manufacturers mentioned that API standard gate valves, globe valves and check valves are mainly used in the petrochemical industry. The power sector mainly uses high temperature pressure gate valves, globe valves, check valves, safety valves and low pressure butterfly valves for the water supply and drainage valves of the power station. The chemical industry mainly uses stainless steel gate valves, globe valves and check valves. 


The metallurgical industry mainly uses low pressure large diameter butterfly valves, oxygen shut-off valves and oxygen ball valves. The urban construction department mainly uses low pressure valves. For example, large-diameter gate valves are mainly used for urban water supply pipelines, mid-line butterfly valves are mainly used for construction, and metal-sealed butterfly valves are mainly used for urban heating. The oil pipeline mainly uses flat gate valves and ball valves. The pharmaceutical industry mainly uses stainless steel ball valves; the food industry mainly uses stainless steel ball valves.


Electric actuators are essential for valve program control, automatic control and remote control. The course of motion can be controlled by stroke, torque or axial thrust. Because the performance and utilization of the electric device depends on the type of valve, the operating procedures of the device and the position of the pipe or equipment of the valve, the correct choice of electric actuator is essential to prevent overload (operating torque is higher than control torque) . Therefore, it is very important to choose the right electric actuator.
