German TreasurevirtueBURKERT solenoid valve is an automation basic component used to control the direction of fluid and belongs to the actuator category; Usually used in mechanical control and industrial valves to control the direction of the medium, thereby achieving control of valve opening and closing. The solenoid valve has a sealed chamber with through holes at different positions, each leading to a different oil pipe. The middle of the chamber is the valve, and there are two electromagnets on both sides. The magnetic coil on either side will attract the valve body to the other side. By controlling the movement of the valve body, different oil discharge holes can be blocked or leaked out. The oil inlet hole is normally open, and hydraulic oil will enter different oil discharge pipes. Then, the pressure of the oil will push the piston of the cylinder, which in turn drives the piston rod, which in turn drives the mechanical device to move. In this way, the mechanical motion is controlled by controlling the current of the electromagnet.

BURKERT solenoid valves can be classified into three main categories based on their principles
Direct acting solenoid valve
Principle: When powered on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens; When the power is cut off, the electromagnetic force disappears, and the spring presses the closing member against the valve seat, causing the valve to close. Characteristics: It can work normally under vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25mm.

Distributed direct acting solenoid valve
Principle: It is a combination of direct action and pilot operated principle. When there is no pressure difference between the inlet and outlet, after being energized, the electromagnetic force directly lifts the pilot small valve and the main valve closing member upward in sequence, and the valve opens. When the inlet and outlet reach the starting pressure difference, after being energized, the electromagnetic force pilot small valve, the lower chamber pressure of the main valve rises, and the upper chamber pressure drops, thereby using the pressure difference to push the main valve upwards; When the power is cut off, the pilot valve uses spring force or medium pressure to push the closing member downwards, causing the valve to close. Features: It can also operate under zero pressure difference, vacuum, and high pressure, but with high power, it must be installed horizontally.

Pilot operated solenoid valve
Principle: When powered on, the electromagnetic force opens the pilot hole, causing the pressure in the upper chamber to rapidly decrease, creating a pressure difference of high and low around the closing element. The fluid pressure pushes the closing element to move upward, and the valve opens; When the power is cut off, the spring force closes the pilot hole, and the inlet pressure quickly forms a lower and higher pressure difference around the closing valve through the bypass hole. The fluid pressure pushes the closing valve to move downward and close the valve. Features: The upper limit of the fluid pressure range is relatively high, and it can be installed freely (customized), but it must meet the fluid pressure difference conditions. 2. Electromagnetic valves are divided into six sub categories based on differences in valve structure, materials, and principles: direct acting diaphragm structure, step-by-step heavy plate structure, pilot diaphragm structure, direct acting piston structure, step-by-step direct acting piston structure, and pilot piston structure.

Selection Guide (Key Parameters)

When choosing a Baode solenoid valve, the following parameters should be clearly defined:

1. fluid mediumWhat is it? (Water, air, steam, oil, chemical solvents?) This determinesValve body materialandsealing material.

• brassUniversal water, air, and oil.

• Stainless steel (316L)Corrosive chemicals, high-purity water, food and medicine.

• PVC/PPStrong acid and strong alkali.

• NBR seal: Universal type.

• FKM/Viton sealResistant to oil, high temperature, and various chemicals.

• EPDM sealResistant to hot water and steam.

2. Operating pressure：*bigWhat are the levels of stress and work pressure? Do we need zero pressure differential start? (Deciding whether to choose direct acting or pilot operated)

3. temperature rangeFluid temperature and ambient temperature.

4. Voltage and powerIs the control voltage DC24V or AC220V? Power consumption requirements? (Need to match with PLC output)

5. pipeline interfaceDiameter (DN) and connection method (internal thread G, NPT, flange)? ）

6. functionIs it normally closed (NC) or normally open (NO)? Two way two-way (2/2) or two way three-way (3/2)?
