ZCT solenoid valve is a kind of common closing guiding solenoid valve, which can operate according to the electric signals generated by the hand switch, pressure controller and other electric appliances. When the winding is switched on, it attracts the main valve's orifice and form a electrified circuit, and when the winding is switched off, the armature tightly closes the main valve's orifice by the spring force and medium pressure to reach the aim of closure.
