30C50-143 Kobelco excavator SK200-8 proportional solenoid valve

product details:

• Solenoid valve structure: (coil, magnet, ejector)

When the coil is connected to the current, the magnetism is generated, and the magnet attracts each other, and the magnet will pull the ejector rod. When the power is turned off, the magnet and the ejector rod are reset, so that the solenoid valve completes the work process

• Principle of direct acting solenoid valve:

When energized, the 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, the spring presses the closing member on the valve seat, and the valve closes.

Features: It can work normally in vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm.

​In order to improve the working reliability and life of the electromagnetic directional valve: Wet electromagnet is used, which does not need to be sealed between the electromagnet and the spool valve push rod, which eliminates the friction at the O-ring seal. Plastic encapsulation, no metal shell is used, which not only ensures insulation, but also facilitates heat dissipation, so it works reliably, with low impact and long life.
