VICKERS, USAWiggs solenoid valveThe iron core inside the magnetic isolation sleeve is completed without dynamic sealing, so external leakage is easily blocked. Electric valve torque control is not easy, which can easily cause internal leakage and even break the valve stem head; The structural type of solenoid valve is easy to control internal leakage and directly reduces to zero. The VICKERS solenoid valve is used for on/off control of liquid and gas pipelines, and is a two position DO control. Generally used for controlling small pipelines. Electric valves are used for analog regulation of medium flow in liquid, gas, and air system pipelines, and are AI controlled. Electric valves can also be used for two position switch control in the control of large valves and air systems. Electromagnetic valves can only be used as switch quantities, are DO controlled, and can only be used for small pipeline control. They are commonly found in pipelines of DN50 and below, and are rarely used above. Electric valves can have AI feedback signals and can be controlled by DO or AO, which are commonly seen in large pipelines and air valves. 1. The switch type solenoid valve is driven by a coil and can only be turned on or off, with a short action time when turned on or off

Wiggs solenoid valveFeatures:

1. External leakage is blocked, internal leakage is easy to control, and safe to use.

2. Flexible movement, reliable function, minimal impact and vibration during operation

3. Low noise, long service life, and minimal pressure loss when fluid passes through hydraulic valves;

When the valve port is closed, it has good sealing performance, small internal leakage, and no external leakage

5. Diverse models and applications

6. The controllable parameters (pressure or flow) are stable, with small changes when subjected to external disturbances, and have the characteristics of compact structure, easy installation, debugging, use, maintenance, and good universality.

VICKERS solenoid valves can be divided into three main categories based on their principles: 1) Direct acting solenoid valves: Principle: When powered on, the solenoid 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. 2) Step by step direct acting solenoid valve: Principle: It is a combination of direct acting 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 powered on, the pressure in the lower chamber of the electromagnetic force pilot small valve increases, and the pressure in the upper chamber decreases, 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. 3) 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 high and low pressure difference around the closing member. The fluid pressure pushes the closing member 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 direct acting diaphragm structure, pilot diaphragm structure, direct acting piston structure, step-by-step direct acting piston structure, and pilot piston structure.
