Step Direct-Action solenoid valve

Principle: It is a direct and pilot-type combination of the principle, when the inlet and outlet no pressure difference, after the electricity, electromagnetic force directly to the pilot small valve and the main valve closed in turn up, the valve opened.

When the inlet and outlet reach the starting pressure difference, after the electricity, the electromagnetic force pilot small valve, the main valve lower chamber pressure rises, the upper chamber pressure drop, thereby using the pressure differential to push the main valve upward; When the power is off, the pilot valve uses the spring force or the medium pressure to push the closing parts, move downward and make the valve close. Features: in 0 pressure differential or vacuum, high pressure can also be * action, but the power is large, requirements must be installed horizontally.
