Introduction of direct-acting solenoid valve

Working principle: When the power is turned on, the electromagnetic coil generates electromagnetic force, which lifts the closing member from the valve seat and opens the valve; when the power is off, the electromagnetic force disappears, and the spring presses the closing member on the valve seat, and the valve closes.

Features: It can work normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25 mm wave distribution direct-acting solenoid valve:

Working principle: The direct-acting type is combined with the pilot type. When there is no pressure difference between the inlet and the outlet, the electromagnetic force directly lifts the pilot valve and the closing part of the main valve upward to make the valve open. When the inlet and outlet reach the starting pressure difference after the power is turned on, the electromagnetic force pilots the small valve, so that the pressure in the lower chamber of the main valve rises, the pressure in the upper chamber decreases, and the main valve is pushed up by the pressure difference; when the power is off, the electromagnetic force or medium pressure pushes The closing piece is pushed down to close the valve.

Features: It can also move under zero pressure difference or vacuum and high pressure, but the power is large, and it must be installed horizontally. Conductive solenoid valve:

Working principle: When the power is turned on, the electromagnetic force will open the guide hole, the pressure of the upper cavity will drop rapidly, and a high-pressure difference between the upper cavity and the lower cavity will be formed around the closing member. The fluid pressure of the normally closed solenoid valve pushes the closing member to move upward, and the valve opens; When the spring force closes the guide hole, the inlet pressure through the bypass hole rises rapidly, forming a high-pressure difference between the lower cavity and the lower cavity around the closing part, and the body pressure pushes the closing part to move down to close the valve.

Features: The upper limit of the hydraulic range is large, and it can be installed arbitrarily (to be customized), but it must meet the hydraulic differential conditions.
