Load-sensitive multi-way valve, the flow rate independent of load; the valve is a section structure, which can be expanded according to the needs, max section is 7 working section; the valve is integrated with an oil return back pressure valve, which adopts a parallel circuit. That can effectively protect the radiator; the flow can be adjusted through the valve spool stroke, and each working section has a pressure compensation function; the working port can be set with a secondary pressure relief valve according to the needs; Control forms: hydraulic control, electro-hydraulic control, manual control; the valve is integrated with the function of switching single and double pumps independently.
