Direct Acting Solenoid Valve

Direct Acting Solenoid Valve, when energized, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, the spring presses the closing member on the valve seat, and the valve closes.

Compared with the electric water control valve and the compressed air solenoid valve, it is a combination of direct action and pilot type. When there is no pressure difference between the inlet and the outlet, after the power is turned on, the electromagnetic force directly closes the small pilot valve and the main valve. The parts are lifted up one by one, and the valve opens. When the inlet and outlet reach the starting pressure difference, after the power is turned on, the electromagnetic force pilots the small valve, the pressure in the lower chamber of the main valve rises, and the pressure in the upper chamber drops, so as to use the pressure difference to push the main valve upward; when the power is turned off, the pilot valve uses a spring The force or medium pressure pushes the closing member, moving downward, causing the valve to close.

Its characteristic is that it can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm. It can also operate under zero pressure difference or vacuum and high pressure, but the power is large and it must be installed horizontally. Our company's common direct acting solenoid valve products are: SLG22 Series Solenoid Valve, VX Series Solenoid Valve, PU220 Series Solenoid Valve.

Direct-acting solenoid valves are mostly used in mechatronic products to achieve electrical control of mechanical actions, such as fuel injectors in automobiles, solenoid valves in ABS, and clutch control valves in automatic transmissions.
