For the troubleshooting of pneumatic valve actuators, we will choose the most suitable pneumatic actuator. The pneumatic actuator with a high cost performance, then we must first understand the type of actuator. The actuator can be divided into pneumatic actuators and electric actuators, which are more commonly used. Actuators are these two, we will choose pneumatic actuators when we buy.
Pneumatic actuators (also known as pneumatic heads), also known as pneumatic actuators or pneumatic devices, are actuators that use compressed air supply pressure to drive opening and closing or adjusting valves. They are mainly composed of cylinders, pistons, gear shafts, and ends. Cover, seals, screws, etc.
Pneumatic valve actuator troubleshooting will choose a more suitable pneumatic actuator, cost-effective pneumatic actuator, then we must first understand the type of actuator
In general, if it is not tightly closed, first check whether the valve has been closed in place. If the leak cannot be sealed after it has been closed in place, then check the sealing surface. For some valves, the sealing pair is detachable, so take it out for grinding and test again.
Actuators are divided into three categories: pneumatic, electric and hydraulic according to their energy forms. They have their own characteristics and are suitable for different occasions. Pneumatic actuators are a category of actuators.
With the rapid development of China's industry, pneumatic valves have become more and more widely used in metallurgy, petrochemical and other fields.
