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.
