After troubleshooting the pneumatic valve actuator, you will choose a more suitable pneumatic actuator, which is more cost-effective. Then you must first understand the type of actuator. The actuator can be divided into a large-caliber solenoid valve into a pneumatic actuator and an electric actuator. The more commonly used are these two types. We will choose pneumatic actuators when purchasing pneumatic actuators.

Then we have to select the actuator according to the size of the air source, the torque required to rotate the valve, if the rotation is too small, the rotation is too large, and the valve life is too short. Generally speaking, a 30% margin of torque is acceptable. Literally, a pneumatic actuator is such an actuator controlled by air pressure. It can adapt to a variety of environments better than electric actuators. The reasonable structure of the direct-acting solenoid valve makes it more powerful and achieves high output torque.

At the same time, it is faster and more responsive than the electric actuator. It is true that electric actuators have many advantages that pneumatic actuators cannot match. The advantages of pneumatic actuators are also unavailable in current electric actuators. Both of them have their own shortcomings and advantages. Therefore, under the continuous development of technology in the future, the cost performance of the two will be even more improved.

Second, we check the installation platform. Each environment chooses an actuator, and the actuator has a standard. If you want to find the corresponding standard according to the valve model, it will not go wrong. And as a pneumatic actuator, in fact, the function of the solenoid valve of the hydraulic pump on the valve is to make the valve device more convenient to use.

And due to the access of the pneumatic actuator, the valve can drive the rapid interlocking of various parts of the valve body when running in the pipeline, and has a certain automatic control effect. Moreover, because the actuator itself is powered by energy, the valve is The drive of the valve body opening and closing parts also has a certain value. Due to the low fluid resistance, this valve plays a role in opening and closing the fluid pipeline.

Common faults are that the valve body does not move, the valve closes less than zero, the pneumatic actuator has no feedback signal, and the signal pressure is unstable. There are also some special faults, such as the vibration of the pneumatic actuator control valve. Then it mainly analyzes the cause of the vibration of the special fault control valve and the treatment method.
