Remote controllability of hydraulic components broadens their range for applications. Hydraulic system design has incorporated remote controls for years in the form of oil and air piloted, and solenoid operated valves. Where precision control is required, electrohydraulic proportional control is coming of age.Applications exist where a remote proportional actuator can provide a previously unavailable level of control. This type of actuator can be used to stroke components such as throttle controls, clutches and brakes or hydraulic pumps and high flow valves. Introduction of electronics, and microprocessors with their potential for high speed and accurate logic, when mated with this actuator, can perform sophisticated tasks.
