The manufacturer tells you how to choose the right electric actuator

With the progress of the times, the intelligence of the valve industry is becoming more and more common, so today Boen electric actuator  manufacturers will teach you how to chooseElectric Actuators correctly:
As we all know, electric actuators are mostly matched with valves to control the opening and closing of valves. Depending on the state of the valve opening, the type of electric actuator used is also different, so it is generally necessary to know the type of valve to be used when choosing a valve electric actuator. For example, gate valves, globe valves, diaphragm valves and other multi-turn valves need to use multi-turn electric actuators, which is what we often call Z-type electric actuators; For valves that do 90-degree rotation such as butterfly valves, ball valves, and dampers, it is necessary to use a partially rotating electric actuator, that is, we use the Q-type electric actuator, quarter-turn electric actuator orSmall Electric Actuatorthat we will mention.
Therefore, the selection ofElectric Actuators should be matched according to the opening and closing mode of the valve:

1. Multi-turnElectric Actuator
The multi-turn electricActuatoris also an electricActuatorthat outputs angular torque, and the difference between it and quarter-turn electricActuatoris that its output shaft rotates more than 360 degrees. Multi-turn electricActuators are suitable for rotary valves that rotate multiple times to complete the opening and closing process, such as gate valves and globe valves.
2. Linear electric actuator
Linear electric actuators output displacement thrust and are suitable for valve types used for disc lift control, such as single-seat control valves and double-seat control valves.
3. Quarter-turn electric actuator
Quarter-turn electric actuators are used in conjunction with rotary valves. The output shaft of the quarter-turn electric actuator rotates less than one week, that is, 360 degrees, such as the rotation angle of butterfly valves, ball valves and plug valves is usually less than 90 degrees, and the rotation of the quarter-turn electric actuator at the position of 90 degrees can realize the opening and closing process of the valve.
Knowing what kind of valve will use what kind of electric actuator, then you need to know how much torque (torque) is required to open the valve, and there are two necessary conditions to know the torque of the valve, that is, the nominal diameter and nominal pressure.
