The proportional control valve is a control valve that continuously and proportionally controls the flow, pressure and direction of the hydraulic system according to the input electrical signal, and its output flow and pressure can not be affected by load changes.
Compared with ordinary hydraulic components, proportional valves have the following characteristics:
1. The electrical signal is easy to transmit, and can easily realize remote control.
2. It can continuously and proportionally control the pressure and flow of the hydraulic system, achieve control of the position, speed, and force of the actuator, and reduce the impact when pressure changes.
3. Reduce the number of components and simplify the oil circuit.
At the same time, the use conditions and maintenance of electro-hydraulic proportional valves are the same as those of general hydraulic components. They are more anti-pollution and more reliable than servo valves.
