Applications& Features

The valve is the latest product developed by our company,it has well met the demands of high-end full load feedback multiple directional control valve with large flow for current domestic large construction machinery. Its high quality full loading feedback function can realize loading sensing servo control, reduce the loading of the pump,power loss and overheating of system, improve the controlling accuracy of construction machinery and minimize energy loss, which may be referred to as best energy-saving product with high accuracy control.

QF28 model full load feedback multiple directional control valve has the function of full load feedback. All working ports can provide correspondent flow as required by the actuating mechanism of the main machine,and ensure that their working speeds will not be affected by load changes. It also has fine inching characteristics.

The valve has the features of high efficiency and energy saving. If the valve fed by loading feedback pump, its center position has almost no pressure loss.

The system will in standby working state with low pressure. In the case of direction changing, the flow provided by oil source is only enough for the actuating mechanism. When the valve is carrying out complex moves,the action speed of individual actuating mechanism will not affect each other. The valve has variety operating modes of manual and hydraulic proportional controls.
