Principle: It is a direct acting and pilot-based combination of principles, when the inlet and outlet pressure ≤ 0.05Mpa, when energized, the electromagnetic force directly to the pilot valve and the main valve closing member turn up, the valve opens. When the inlet and outlet pressure <0.05Mpa, power, the electromagnetic force first open the pilot valve, the lower pressure in the main valve rises, the pressure on the cavity down, so use the pressure valve to push the main valve up; power off, the pilot valve And the main valve using spring force or medium pressure to push the closure, move down, the valve closed. Features: Zero pressure or vacuum, high pressure can also work reliably, but the power is larger, requiring vertical installation.
