Proportional Control Valve Profile
The proportional control valve is mainly used for open-loop control (open loop control); proportional control valve output with the input signal is proportional to, and the proportional control valve solenoid coil magnetic size is proportional to current.
Traditional types of hydraulic control valves, only the hydraulic setting control, for example: the pressure valve under the pressure in a set move, flow control valve to maintain the flow through the set, the directional control valve for the flow direction through / off switch. control valve system are subject to some restrictions, as technology advances, many of the hydraulic system requirements for flow and pressure continuous or in proportion to the change of the control valve input signal. hydraulic servo system are able to meet its requirements, and high precision, but for most of the industries, they do not require the system to have such a high quality, and hope that under the conditions that guarantee the control performance, low-cost, reliable, easy maintenance, so the proportional control valve is developed in this context.
