Principle
It is a direct-acting and pilot-operated combination principle, when the inlet and outlet pressure difference, energized, the electromagnetic force directly to the pilot valve and main valveoff pieces turn lift valve opens. When the inlet and outlet to start pressure, energized, the electromagnetic force pilot valve, the main valve of the inferior vena pressure increase in pressure drop of the upper chamber, to take advantage of the differential pressure to the main valve is pushed upwards; Power, the pilot valve with a spring The force or pressure of the medium to promote the closure member, and moved downward, so that the valve is closed.

Features:
1. Zero pressure or vacuum, high pressure also can be action, but the power requirements must be mounted horizontally.
2. The 2W series zero differential valves have the thread size range from 1/8 to 2.

Attention:
Before installing the solenoid valve, the first clear tube Tract dust debris, and install Filter means connecting pipe, note ended the vent strap around not exceed the teeth end face.
Used in gas, heavy oil and corrosive fluid, etc. Various kinds of special occasions, additional order.
