Electric gate valve is a kind of valve with linear motion. It is matched with Z-type multi rotation actuator, including switch type and intelligent type. This valve is easy to operate. It is a common opening and closing valve. It uses the up and down work of the ram to connect and shut off the fluid medium in the pipeline. It is widely used in electric power, metallurgy, petroleum, chemical industry, papermaking, s

The action force distance of electric valve is larger than that of ordinary valve. The opening and closing speed of electric valve can be adjusted. It has simple structure and easy maintenance. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metal and radioactive media. Electric valves are usually composed of electric actuat

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
