Double-controlled flameproof solenoid valve

Overview:

The double-controlled flameproof solenoid valve is an automatic control valve used in environments with explosion hazards, which achieves the opening and closing of the valve through double-coil control. The double-controlled flameproof solenoid valve has two coils, which respectively control the opening and closing of the valve. When a coil is energized, the valve reverses direction and does not return to its original position after power-off (without a spring structure), maintaining the current unobstructed state. The valve will return to its original position only when the other coil is energized. This design avoids the coil heating problem caused by the single-controlled solenoid valve remaining open due to long-term power-on, enabling the coil to work stably for a long time and also achieving more precise control of the valve.
