Analog amplifiers for high-response valves


Control amplifier for standard servo solenoid valve

The amplifier VT-VRRA1 controls standard servo solenoid valves with DC-LVDT feedback for direct operated 4WRPH..L-2X and 2-stage 4WRL..-3X. These are basic amplifiers. Since these components are normally used in closed loop applications, other features like ramp, time, and spool compenstion (jump) are not needed.
