0927 Two Position Two-way Pilot Operated Diaphragm Solenoid Valve
Application scope and characteristics
1.The pressure can reach 16 kg.
2.The external leakage is blocked,the internal leakage is easy to control,and the use is safe.
Principle
When powered on,the electromagnetic force drives the pilot valve to open the pilot valve,the pressure of the upper chamber of the main valve drops rapidly,forming a pressure difference in the upper and lower chambers of the main valve,relying on the medium pressure to push the main valve closing parts up,and the valve is opened;When the power is off,the spring force closes the pilot valve ,and the inlet medium pressure quickiy enters the upper chamber of the main valve through the pilot hole to form a pressure difference in the upper chamber,so that the main valve is closed.
