SLP diaphragm solenoid valve is a pilot operated structure solenoid valve, and its core functional characteristics lie in its working principle and design:

Working principle: The valve controls the opening and closing of the pilot hole through electromagnetic force, and uses the pressure difference on both sides of the diaphragm to achieve the opening and closing of the valve. When powered on, the pilot hole opens, and the pressure above the diaphragm decreases, forming a pressure difference of lower and higher. The fluid pressure pushes the diaphragm to move upward, and the valve opens; When the power is cut off, the spring force causes the pilot hole to close, and the inlet pressure enters the chamber above the diaphragm through the bypass hole, forming a pressure difference of high above and low below. The fluid pressure pushes the diaphragm to move downward, and the valve closes. ‌

Product specifications: Its nominal diameter range is usually DN15 to DN100, and it adopts a diaphragm structure. ‌
