Electric ball valve is often used in our life, but we often can't distinguish the difference between electric ball valve and solenoid valve. Next, I'll explain how to distinguish the difference between electric ball valve and solenoid valve. Let's take a closer look at these two devices. Although the functions of electric ball valve and solenoid valve are almost the same, their action mechanism is very

1. The box body is a rain proof box with inner and outer double doors, and the outer door is equipped with a perspective glass window to observe the opening of the valve at any time; 2. The opening of the valve can be displayed by pointer or LCD on the controller panel, and the zero and full degree can be set automatically. The panel of the controller is provided with valve opening, valve closing, local / remote c

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
