Pneumatic ball valve includes valve body, ball, valve stem and pneumatic actuator. A bracket is arranged on the valve stem between the valve body and the pneumatic actuator. The valve stem between the bracket and the valve stem is sequentially provided with a packing gland, a packing and a packing pad from bottom to bottom. A sliding bush is arranged between the valve stem and the valve body, one end of the valve bod

Electric actuator is a commonly used transmission device in industrial production systems. The main function of this device is to control the transmission device, so as to complete various complex assembly line production tasks. Since it is directly related to the daily production of the factory, the quality of the equipment must be guaranteed during operation. Customers can judge according to the three aspects of eq

During on-site maintenance, we will encounter that the solenoid valve does not convert and the cylinder does not move. What should we do then? First of all, it is necessary to determine whether there is a power supply. Generally, the rated voltage of the solenoid valve is AC 220v or DC 24v. Then, when using DC power to drive the solenoid valve, the positive and negative poles must be connected correctly, and the po

Note one For pilot-operated solenoid valves, it is necessary to check whether the pressure difference in the pipeline is too small. If the pressure difference is too small, the solenoid valve cannot work normally. In this case, a direct-acting solenoid valve is required. And the pressure difference is too large, far exceeding the design value of the solenoid valve, and it cannot work normally, so a high-pressure sol

Solenoid valve is an industrial equipment controlled by electromagnetic, which adjusts the direction, flow, speed and other parameters of the medium in the industrial control system. When the solenoid valve is not powered on, the valve needle blocks the passage of the valve body under the action of the spring, and the solenoid valve is in the cut-off state. When the coil is powered on, the coil generates a magneti

Solenoid valve is an automatic basic component used to control fluids. It belongs to the actuator and is not limited to hydraulic and pneumatic. Different solenoid valves play a role in different positions of the control system, the most commonly used are check valves, safety valves, directional control valves, speed control valves, etc. In principle, solenoid valves are divided into three categories: direct-actin
