The characteristics of the pilot solenoid valve:
Principle: when electrifying, the electromagnetic force opens the pilot hole, the pressure of the upper chamber drops rapidly, forms a low high pressure difference around the closed part, the fluid pressure pushes the closure to move upwards and the valve opens; when the power is broken, the spring force closes the pilot hole, and the entrance pressure passes through the bypass hole to form lower lower around the closed valve parts. With high pressure difference, the fluid pressure pushes the shut-off parts to move downwards and close the valve.
Features: the upper limit of fluid pressure range is high, and it can be installed at any time.
2. The difference between the valve structure and the material from the valve structure and the material is divided into six branches: direct moving diaphragm structure, step direct moving diaphragm structure, pilot diaphragm structure, direct moving piston structure, step direct piston structure, and pilot piston structure.
3. The solenoid valve is classified according to its functions: water solenoid valve, steam electromagnetic valve, refrigerating electromagnetic valve, low temperature electromagnetic valve, gas electromagnetic valve, fire fighting solenoid valve, ammonia solenoid valve, gas electromagnetic valve, liquid electromagnetic valve, miniature solenoid valve, pulse solenoid valve, hydraulic solenoid valve, electric solenoid valve, oil solenoid valve and direct current solenoid valve. High pressure electromagnetic valve, explosion-proof electromagnetic valve and so on.
