2L series 2-way piston normally closed steam hot water solenoid valve 3/8 2
steam hot water solenoid valve working principle
Normally closed steam solenoid valve coil is energized, the armature in the electromagnetic force to drive from the deputy valve Seti, fluid through the secondary valve flow down the main valve on the cup, reducing the role of the main valve cup pressure, when the main reduce the pressure on the valve cup to a certain value, the armature drive the main valve cup, and leaving the use of pressure to open the main valve cup, medium flow. Coil power, the electromagnetic force disappears, the armature is reset by its own weight fall. At the same time rely on media pressure, the primary and secondary valve to be tightly closed.
