The German Rexroth solenoid valve has through holes at different positions, each connecting to a different oil pipe. Inside the chamber is a piston, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. Controlling the movement of the valve body opens or closes different drain holes. The inlet hole is always open, allowing hydraulic oil to enter the different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.

German Rexroth solenoid valves are used in hydraulic systems to control the opening and closing of hydraulic circuits or to change the direction of fluid flow. They typically feature a valve core that slides under the electromagnetic force of a coil. The different positions of the valve core result in different flow paths for the solenoid valve. The number of working positions of the valve core determines the solenoid valve's dimensional accuracy; the number of ports on the valve body determines the number of flow paths. After installation, all interfaces should be aligned. The "working position" refers to the position of the valve core. When the coil is not energized, the valve core is in position A; when the coil is energized, it is in position B. The valve core in these different positions either connects or disconnects the various interfaces. A two-position solenoid valve means the valve core has two different operating positions (open and closed). Two-way and three-way solenoid valves refer to valves with two or three channels on the valve body; for example, a two-position two-way solenoid valve has one inlet and one outlet (two channels, the most common); a two-position three-way solenoid valve controls liquids with one inlet and two outlets (one normally open and one normally closed); a pneumatic directional solenoid valve has one inlet, one outlet, and one exhaust; a hydraulic solenoid valve has one inlet, one outlet, and one return oil. Domestic and international solenoid valves are theoretically divided into three main categories (direct-acting, step-direct-acting, and pilot-operated), and further subdivided into six subcategories based on differences in valve disc structure and materials (direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot-operated piston structure). Direct-acting solenoid valve: Principle: When energized, the solenoid coil generates electromagnetic force to lift the sealing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the sealing element onto the valve seat, closing the valve. Features: Can operate normally under vacuum, negative pressure, and zero pressure, but the nominal diameter generally does not exceed 25mm. Distributed direct-acting solenoid valve: Principle: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, after energization, the electromagnetic force directly lifts the pilot valve and the main valve sealing element sequentially upwards, opening the valve. When the inlet and outlet reach the starting pressure difference, after energization, the electromagnetic force pilots the small valve, the pressure in the lower chamber of the main valve rises, and the pressure in the upper chamber falls, then the pressure difference pushes the main valve upwards; when de-energized, the pilot valve uses spring force or medium pressure to push the sealing element downwards, closing the valve. Features: Reliable operation even at zero pressure difference, vacuum, or high pressure, but requires higher power and necessitates a horizontally mounted pilot-operated solenoid valve. Principle: When energized, electromagnetic force opens the pilot orifice, rapidly reducing the pressure in the upper chamber and creating a pressure differential around the sealing element. The fluid pressure pushes the sealing element upwards, opening the valve. When de-energized, spring force closes the pilot orifice, and the inlet pressure quickly creates a pressure differential around the closing element through the bypass orifice, causing the fluid pressure to push the sealing element downwards, closing the valve.
Characteristics of German Rexroth Solenoid Valves
Domestic and international solenoid valves are broadly classified into three categories based on their operating principles (direct-acting, step-direct-acting, and pilot-operated). Furthermore, based on differences in valve disc structure and materials, and fundamental principles, they are further divided into six subcategories (direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot-operated piston structure). Direct-acting solenoid valve: Principle: When energized, the solenoid coil generates electromagnetic force to lift the closing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing element onto the valve seat, closing the valve. Features: Can operate normally under vacuum, negative pressure, and zero pressure, but the nominal diameter is generally no more than 25mm. Distributed direct-acting solenoid valve: Principle: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, after energization, the electromagnetic force directly lifts the pilot valve and the main valve closing element sequentially upwards, opening the valve. When the inlet and outlet reach the starting pressure difference, after energization, the electromagnetic force pilots the small valve, increasing the pressure in the lower chamber of the main valve and decreasing the pressure in the upper chamber, thus using the pressure difference to push the main valve upwards; when de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve. Features: Can reliably operate under zero pressure difference, vacuum, or high pressure, but requires higher power and must be installed horizontally. Pilot-operated solenoid valve: Principle: When energized, electromagnetic force opens the pilot orifice, causing a rapid drop in pressure in the upper chamber. This creates a pressure differential around the closing element, with lower pressure at the top and higher pressure at the bottom. The fluid pressure pushes the closing element upwards, opening the valve. When de-energized, spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downwards, closing the valve.
