Rexroth Solenoid Valve 4WRZ10E50-71 6EG24N9ETK4M 1kgs/100pcs Gross Weight

Solenoid valve is an industrial equipment controlled by electromagnetic, is used to control the basic components of fluid automation, belongs to the actuator, is not limited to hydraulic, pneumatic. Used in industrial control systems to adjust the direction of media, flow, speed and other parameters.

The solenoid valve can be combined with different circuits to achieve the desired control, and the precision and flexibility of the control can be guaranteed. There are many kinds of solenoid valves, different solenoid valves play a role in different positions of the control system, the most commonly used are check valves, safety valves, direction control valves, speed regulating valves and so on.

Principle of direct-acting solenoid valve: When energized, the electromagnetic force generated by the electromagnetic coil lifts the closing part from the seat, and the valve opens; When the power is off, the electromagnetic force disappears, the spring presses the closing part on the seat, and the valve is closed. Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter is generally not more than 25mm.

Step direct acting solenoid valve principle: it is a combination of direct acting and pilot principle, when there is no pressure difference between the inlet and the outlet, after the power is turned on, the electromagnetic force directly lifts the pilot small valve and the main valve closing part in turn, and the valve opens. When the inlet and outlet reach the starting pressure difference, after power, the electromagnetic force pilot small valve, the main valve lower chamber pressure rises, the upper chamber pressure drops, so as to use the pressure difference to push the main valve upward; When the power is off, the pilot valve uses spring force or medium pressure to push the closing part and moves downward to close the valve. Features: It can also be operated at zero pressure difference or vacuum and high pressure, but the power is large, and it must be installed horizontally.
