    BKH Ball Valves/BKH3K Ball Valves Manufacturers introduces the working principle of hydraulic valves:

    1. The basic structure of a hydraulic valve mainly includes a valve core and a control device that drives the valve core to move relative to the valve body. The main forms of the valve core are roughly divided into ball valves, spool valves, and poppet valves; in addition to the valve body holes or valve seat holes that match the valve core, there are also oil inlet, outlet, and drain ports for external oil pipes; The device that drives the valve core to move relative to the valve body can be a manual adjustment mechanism, a spring or an electromagnet, and in some cases, it is driven by hydraulic pressure.

    2. The hydraulic valve uses the relative movement of the valve core in the valve body to control the opening and closing of the valve port and the size of the opening to achieve pressure, flow, and direction control. When the hydraulic valve is working, the relationship between the size of the valve port of all valves, the pressure difference between the valve inlet and outlet ports, and the flow rate through the valve are in accordance with the orifice flow formula (q=KA·Δp m), but various valves The controlled parameters are different.
