flow and direction. The control element includes a pressure control valve, flow control valve and the directional control valve is a valve (also known as the valve) and the like. The pressure control valve is divided: relief (safety valve), valves, sequence valves, pressure control relays, pressure control valves mainly for protection, detection effect, prevent overpressure damage to the hydraulic system, the hydraulic system in the lifting platform, commonly the pressure control valve is a pressure relief valve, mainly from the effect of limiting the lifting platform overload. Common flow valve comprising: a throttle valve, regulating valve (proportional valve), triage and set flow control valve. Hydraulic lift to adjust the level of the hydraulic system commonly used valves and diverter valve, regulating valve (proportional valve) is generally controlled by current or voltage to the solenoid control valve opening, the purpose of adjustment of the hydraulic oil flow, and ultimately regulate the speed of the lifting platform. Shunt valve used in a pumping station to control multiple locations lift lifting platform, mainly multi-platform lifting platform synchronized movements. Directional control valve includes: a one-way valve, check valve, shuttle valve, valve, etc., common direction valve lift platform control valve is mainly used to switch the oil, hydraulic oil to achieve commutation. Hydraulic control system of hydraulic lifting platform components main role is to regulate the flow of hydraulic oil, hydraulic oil flow adjustment, protect the hydraulic system security role, and ultimately speed control and lift switch.
