Product Description
Rexroth VT-TSPD-1-20/V0/0 (Part No. R901076414) is a digital proportional valve amplifier of the VT-TSPD family, designed for hydraulic proportional valves with built-in position feedback. It receives setpoint signals (±10V or 4–20mA) from the master controller, runs closed-loop control algorithm and outputs high-current PWM signals to drive proportional solenoids. It reads LVDT spool position feedback for closed-loop correction and supports software parameter setup, ramp function, fault diagnosis and alarm output. With fast dynamic response and excellent repeatability, it matches proportional directional, pressure and flow control valves with position sensors. It is widely used in precision closed-loop hydraulic systems and serves as a common spare part for hydraulic presses, injection molding machines and turbine hydraulic control systems.
