Kas ir elektriskais vadības vārsts?

The elektriskais vadības vārsts is a hydraulically operated valve with a solenoid valve as a guide valve. It is often used for automatic control in water supply and drainage and industrial systems. The control response is accurate and fast, and the pipeline system is remotely opened and closed according to electrical signals to realize remote operation. Can replace gate valve and butterfly valve for large electric operating system. The valve closing speed is adjustable, and the valve closes smoothly without pressure fluctuation. The valve is small in size, light in weight, simple in maintenance, convenient in use, safe and reliable. The solenoid valve can choose AC 220V, or DC 24V, which can be normally open or normally closed according to various occasions.

How Electric Control Valve works:
When the valve feeds water from the inlet, the water flows through the needle valve and enters the main valve control room. When the solenoid pilot valve is opened, the water in the control room flows out through the solenoid pilot valve and ball valve. The opening of the ball valve is greater than the opening of the needle valve, the pressure in the main valve control room is very low, and the main valve is in a fully open state.
When the solenoid pilot valve is closed, the water in the control chamber of the main valve cannot flow out, and the pressure in the control chamber increases, pushing the diaphragm to close the main valve.
