Energized, the electromagnetic force open the pilot hole, the upper chamber pressure decreased rapidly

Principle: power, the electromagnetic force open the pilot hole, the upper chamber pressure  mcb circuit breaker  rapidly formed around the closed lower on the high pressure, the fluid pressure to promote off pieces to move up, the valve opens; energized, the spring force to the pilot hole is closed, the inlet pressure chamber  mcb circuit breaker  the bypass hole quickly formed around the closing valve under high pressure low on fluid pressure to promote off pieces moving down, close the valve.
Features: Fluid pressure range limit is higher, can be any installation (to be customized) but must meet the conditions of fluid pressure.
Solenoid valve  Voltage stabilizer  and materials from the different and the difference principle, is divided into six branches subcategories: direct acting diaphragm structure, step by step direct-acting diaphragm structure, the pilot diaphragm structure, direct-acting piston structure, step by step direct-acting piston structure, the pilot piston structure.
