Simple servo systems, which do not use hydraulic servo valves or high-speed proportional valves, can be made by controlling the pump rotation speed with a…
Servo amplifiers drive servo valves, based on the same principles as the amplifiers for proportional electro-hydraulic control. Table 9.3 lists the functions and features of…
The valves directly drive a spool with a small and high-power linear motor. Direct drive servo valves electrically send the spool position data to the…
Nearly all types of servo valves are based on common principles. Electro-hydraulic two-stage servo valves generally operate with force feedback. Given that valve pressure drop…
A servomechanism is an automatic control system designed to operate in accordance with input control parameters. The mechanism continuously compares the input signal to the…
These valves are a combination of a proportional electro hydraulic pilot relief valve and a pressure reducing and relieving valve. They can control hydraulic system…
These valves are a combination of a directional and flow control valve and a power amplifier. The flow rate can be controlled by changing an…
These valves consist of a proportional electro-hydraulic relief valve, a power amplifier, and a pressure sensor. They can control hydraulic system pressures proportionally to the…
These valves contain a combination of an amplifier-integrated proportional valve, pressure sensor, and displacement sensor in order to improve the functionality and ease of use.…
