Hydraulic Servo Control Solution – BOSCH Rexroth WV45-RGC2 | VT-VSPA Series
The BOSCH Rexroth WV45-RGC2 Amplifier Card (P/N: 0811405119) is a precision analog amplifier module engineered for closed-loop control of hydraulic proportional and servo valves. Designed for demanding industrial environments, this card delivers stable, repeatable valve positioning with integrated ramp, dither, and enable functions — making it the preferred choice for OEM machine builders and MRO replacement applications worldwide.
Where This Product Is Used
- Injection Molding Machines — Controls proportional pressure/flow valves for precise clamp force and injection speed regulation.
- Metal Forming Presses — Manages servo valve positioning in hydraulic press brakes and stamping lines for repeatable stroke control.
- Steel Mill Rolling Equipment — Provides high-bandwidth valve drive for AGC (Automatic Gauge Control) loops in hot and cold rolling mills.
- Marine & Offshore Hydraulics — Used in steering gear, stabilizer fin, and deck crane control systems requiring reliable proportional valve amplification.
- Test Bench & Simulation Rigs — Integrated into servo-hydraulic fatigue and materials testing machines for precise force/displacement control.
- Plastic Extrusion Lines — Regulates melt pressure and die gap via proportional valve control for consistent product dimensions.

Application-Specific FAQ
Q: Is the WV45-RGC2 compatible with the VT-VSPA1-1-10/V0/0 amplifier rack?
A: Yes. The WV45-RGC2 card is designed for the VT-VSPA Euro-card rack system. Confirm slot assignment and jumper settings with your system documentation before installation.
Q: Can this card control a servo valve (not just proportional)?
A: The RGC2 variant is optimized for proportional valve control. For high-performance servo valve applications requiring <1% hysteresis, consult Konmask for the appropriate servo amplifier card.
Q: What is the lead time for a replacement WV45-RGC2?
A: In-stock units ship within 1–3 business days. For sourced or refurbished units, typical lead time is 7–15 business days. Contact us to confirm current stock.
Q: Do you provide a warranty?
A: Yes. New surplus units carry a 12-month warranty against manufacturing defects. Tested refurbished units carry a 6-month functional warranty. Terms available on request.
Q: Can you supply the complete VT-VSPA rack system?
A: Yes. Konmask.com can source complete rack assemblies, individual cards, and associated proportional valves. Submit your full BOM for a consolidated quote.
