Audited Supplier SL20PB2-4X/ type is a poppet valve structure of the hydraulic control check valve, which allows the free flow of oil when closed. The REXROTH valve is designed to isolate the hydraulic system. It is a safety measure to prevent the hydraulic system from breaking and also to prevent the actuator from crawling and drifting when the hydraulic pressure is turned off. The REXROTH check valve structure consists of a body, spool, compression spring and control piston, as well as an optional pressure release ball valve.
REXROTH check valve is a valve that controls the liquid pressure to reverse the flow of the check valve. This kind of valve has a great position in the hydraulic support device of coal mine machinery. Different from the ordinary check valve, the SL20PB2-4X/ check valve also has a control oil K, when the control oil is not connected to the pressure oil, its working principle is the same as the ordinary check valve, the pressure oil only flows from the oil inlet to the oil outlet, can not counterflow. Use the ejector rod to open the check valve and connect the oil outlet.

Basic Functions
The SL20PB2-4X/ check valve can also be used to separate the oil loop and prevent interference. The SL20PB2-4X/ check valve can be combined with other valves to form a composite valve.
For the ordinary hydraulic control check valve, in the control port without control pressure, the operation mode is the same as the ordinary check valve; When the control port is connected to the control port, the oil can flow freely in both directions.
Its main use is: the hydraulic cylinder can be locked, as a vertical hydraulic cylinder support valve, play the role of pressure.
Principle of Operation
Check valve and check valve are integrated to form a pressure valve. This valve is both a discharge valve, a relief valve, and sometimes a relief valve. It controls the oil path through all reversing valves and the discharge path described above. When each directional valve is in the neutral position, the control oil channel of the SL20PB2-4X/ check valve is connected to the oil tank through the directional valve of each channel.
