Step-by-step direct-acting solenoid valve
The step-by-step direct-acting solenoid valve combines the working principles of direct-acting and pilot-operated solenoid valves. When there is no pressure difference at the inlet and outlet or the pressure difference is too small to move the valve, the electromagnetic force is used to open the valve. (Same as direct-acting solenoid valve); When the inlet and outlet pressure difference can push the valve to move, use the pressure to open the valve (same as the pilot solenoid valve); after the power is off, there is no pressure difference or electromagnetic force, the valve is in the spring Closed under the action.
