Three principles of CKD solenoid valve

The ckd solenoid valves are divided into three main categories in principle:
1. Direct-acting solenoid valve: Principle: When energized, the CKD electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; when the power is off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, the valve shut down. Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm.

2. Pilot-operated solenoid valve: Principle: When energized, the CKD electromagnetic force opens the pilot hole, the pressure in the upper chamber drops rapidly, and a pressure difference between the upper and lower parts is formed around the closing member, and the fluid pressure pushes the closing member upward to move the valve to open; When the power is off, the spring force closes the pilot hole, and the inlet pressure passes through the bypass hole to form a lower low and high pressure difference around the valve member, and the fluid pressure pushes the closing member downward to close the valve. Features: The upper limit of the fluid pressure range is high, it can be installed arbitrarily (customized), but the fluid pressure difference condition must be met. CKD solenoid valve is divided into six sub-categories: the direct-acting diaphragm structure, the step-by-step direct diaphragm structure, the pilot diaphragm structure, the direct acting piston structure, and the difference between the valve structure and the material. Step direct-acting piston structure, pilot piston structure.

3, step-by-step direct-acting solenoid valve: principle: it is a combination of direct-acting and pilot-type, when there is no pressure difference between the inlet and the outlet, after the power is applied, the electromagnetic force directly puts the pilot small valve and the main valve closing member Lift up in turn and the valve opens. When the inlet and outlet reach the starting pressure difference, after the energization, the electromagnetic force leads the small valve, the pressure of the lower chamber of the main valve rises, and the pressure of the upper chamber drops, so that the main valve is pushed upward by the pressure difference; when the power is off, the pilot valve uses the spring The force or medium pressure pushes the closure and moves down to close the valve. Features: It can be operated at zero pressure difference or vacuum or high pressure, but the power is large, and it must be installed horizontally.
