solenoid valveThere is a sealed chamber inside, with through holes at different positions, each leading to a different oil pipe of the solenoid valve. The middle of the chamber is a valve, and there are two electromagnets on both sides. The magnetic coil on which side is energized will attract the valve body to which side. By controlling the movement of the valve body, different oil discharge holes will 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, and the piston rod drives the mechanical device to move. In this way, the mechanical motion is controlled by controlling the current on and off of the electromagnet.
Precautions for installation of solenoid valve:
1. When solenoid valves are applied in pneumatic systems and connected to pneumatic components, they are generally wrapped with a sealing tape; It is also wrapped to achieve the sealing function. But experienced friends will definitely encounter such a phenomenon: even though it is a brand new component, it always leaks air when trying it out. One of the major reasons for this is also the most common one.

But experienced friends will definitely encounter such a phenomenon: even though it is a brand new component, it always leaks air when trying it out. One of the main reasons, which is also the most common reason, is that some of the raw materials were not wrapped correctly, and some of them ran into the gas path; This requires attention to a positive and negative sequence when winding the raw material tape. Please experiment and experience this on your own, apprentices.
3. For high currentsolenoid valveRelays must be installed at the front end; Especially for the solenoid valve in the oil pressure system, due to the high current, if a relay is not installed, the lifespan of the solenoid valve will be very short.
