4720726280 MAN Solenoid Valve

  The function of diesel Solenoid valve is to use electric energy flowing through the coil to generate electromagnetic suction to attract the valve core, divided into normally open and normally closed two categories, usually used to cut off the flow of oil, water, gas and other substances.

  Solenoid Valve is an industrial equipment controlled by solenoid, is an automation basic component used to control fluids, belongs to actuators, and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust media direction, flow, speed and other parameters. Solenoid valves can be combined with different circuits to achieve the expected control, and the accuracy 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, directional control valves, speed regulating valves, etc.

  First, the working principle of the solenoid valve has a closed cavity, there are through holes in different positions, each hole is connected to a different oil pipe, the middle of the cavity is a piston, both sides are two electromagnets, which side of the magnet coil energized valve body will be attracted to which side, by controlling the movement of the valve body to open or close different oil discharge holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil discharge pipes, and then push the piston of the cylinder through the pressure of the oil, the piston drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current on-off of the electromagnet. In principle, it is divided into three categories: direct-acting solenoid valves, step-by-step direct-acting solenoid valves, and pilot-operated solenoid valves.
