Where are hydraulic actuators commonly used


Hydraulic actuators are simple, compact, and small in size. Stable and reliable transmission, without buffering or impact. Different hydraulic oils can be used as needed, which can operate within the temperature range of -45 ℃ to+120 ℃ and have explosion-proof properties. It can obtain large output torque and is suitable for any specification. The output torque can be accurately adjusted through a constant pressure relief valve, including the adjustment of opening and closing torque, and can even be directly reflected through hydraulic instruments. In the event of a sudden power outage, the accumulator can still be used for one or more power operations, which is of special significance for the automatic emergency shut-off valve and inlet discharge valve of long-distance pipelines.

The functions and uses of AW series pneumatic actuators


The AW series pneumatic actuators are suitable for valves that rotate at 90 ° C (1/4 turn). Such as ball valves, butterfly valves, plug valves, etc. This product is designed and manufactured according to JIS standards, and the connection with the valve adopts the international standard ISO5211. When selecting and installing AW pneumatic actuators, the first step is to determine the torque of the valve and consider the pipeline medium. Water vapor or non lubricating media can increase the * * value by 25%; Non lubricating dry gas medium can increase * * value by 60%; Non lubricating use can improve the performance of granular powder media by 100%. Whether it is clean or not, increase the * * value of the friction lubrication medium by 20%, and then find a double acting or single acting torque gauge based on the working pressure of the air source to obtain an accurate actuator model.

Daily maintenance and management of electric valves


1. The load of pneumatic devices is relatively large, which can adapt well to some high torque outputs. Although this is the case, electric actuators can now withstand relatively large loads and catch up with the level of pneumatic loads. Therefore, this point is only for your reference, after all, the situation is different. 2. Compared to other devices, pneumatic devices have lower requirements for the working environment. They can be used in some flammable and explosive situations, and even in many harsh environments such as dusty, strong magnetic, high radiation, or strong vibration. 3. The pneumatic device operates quickly and responds very quickly.

The purpose and characteristics of electric actuators


The purpose of electric actuators: When it comes to the purpose of electric actuators, it is actually to convert the rotary motion of the motor into the desired operation (linear operation/rotary operation) to achieve the operation that the electric actuator needs to achieve. And it has remote control function and ground control function, which can be operated electrically or manually.

Classification and selection of valve electric actuators


Valve electric actuators can be divided into three types based on the movement mode of the output shaft. 1. Partial rotary electric actuator, the output shaft of the partial rotary electric actuator rotates less than one turn, with a rotation angle of less than 360 degrees, and the output shaft rotates 90 degrees to achieve the opening and closing process of the valve. Partial rotary electric actuators are used in conjunction with butterfly valves, ball valves, and plug valves. 2. Multi turn electric actuator, the output shaft of the multi turn electric actuator rotates more than 360 degrees, generally requiring multiple turns to achieve the opening and closing action of the valve. Multi turn electric actuator is mainly used in conjunction with gate valves and globe valves.
