Pilot operated solenoid valve connector
Principle: when energized, the electromagnetic force opens the pilot hole, the pressure in the upper chamber drops rapidly, forming a low and high pressure difference around the closing part, the fluid pressure pushes the closing part upward, and the valve opens; In case of power failure, the spring force closes the pilot hole, the inlet pressure quickly passes through the bypass hole, and the chamber forms a pressure difference between lower and upper around the valve closing part, and the fluid pressure pushes the closing part to move downward to close the valve.
Features: the upper limit of fluid pressure range is high, which can be installed arbitrarily (customized), but must meet the conditions of fluid pressure difference.
2. Solenoid valve connectors
are divided into six sub categories: direct acting diaphragm structure, step-by-step direct acting diaphragm structure, pilot diaphragm structure, direct acting piston structure, step-by-step direct acting piston structure and pilot piston structure.
3. Solenoid valve connectors
are classified according to their functions: water solenoid valve, steam solenoid valve, refrigeration solenoid valve, low-temperature solenoid valve, gas solenoid valve, fire solenoid valve, ammonia solenoid valve, gas solenoid valve, liquid solenoid valve, micro solenoid valve, pulse solenoid valve, hydraulic solenoid valve, normally open solenoid valve, oil solenoid valve, DC solenoid valve, high-pressure solenoid valve, explosion-proof solenoid valve, etc.
