Product Description:

solenoid valve is a combination of direct-acting and pilot-operated principle. Normally closed --- When there is no pressure difference between the inlet and the outlet, the electromagnetic force directly opens the pilot hole after energization, connects the main valve piston to lift up in turn, and the valve opens; when the inlet and outlet reach the starting pressure difference, after energization, the electromagnetic force First open the pilot hole, the pressure in the upper cavity of the main valve piston drops, so that the pressure difference and electromagnetic force are used to pull the main piston, and, the upper cavity of the main piston is pressurized, pushing the main piston down and the valve closes. Normally open is the opposite of normally closed.
