Dump truck pneumatic control hydraulic valve set is mainly composed of pneumatic control valve, limit valve and pneumatic hydraulic lifting valve. QF33.1-00 air control valve is three positions five ways double directional operation valve, which control the lift, drop and stop of hydraulic lift valve. When using hydraulic valve with proportional drop function, the falling speed of the tank body can be controlled by controlling the movement of the valve stem through the air control valve. This valve has advanced performance, compact structure, small size, light weight and easy installation. QF22.1-00 limit valve is two positions three ways air valve with push - rod type, which is used to limit the travel of working mechanism. QF22.1-00 limit valve is two position three ways air valve with push-rod type, which is used to limit the travel of working mechanism. HCQF-G25L pneumatic hydraulic lifting valve is three positions three ways pneumatic directional valve. The lifting position is provided with overflow valve and pressure gauge interface to make the pressure can be adjusted to prevent system overload; It the descending position, the hydraulic flow can be proportional control through the pneumatic pilot valve. The valve has large flow and high pressure and can be controlled remotely by air control.
★ Built-in overflow valve: pneumatic hydraulic lifting valve has built-in pilot overflow valve to control system pressure.
★ Pneumatic reversing: pneumatic hydraulic lifting valve stem and cylinder piston rigid connection, can achieve lift, drop and stop function.
★ Proportional control: the pneumatic control valve is a three positions five ways double directional operation valve, which can realize the pilot proportional control in the descending action, and the speed control of the descending action can be realized when used together with the pneumatic and hydraulic lifting valve.
★ Stroke control: limit valve is used to limit the stroke of working mechanism
