REXROTH VT-VSPA2-1-20/V0/T1 Proportional Throttle Valve (Cartridge Design)

Description

Overview​

Key Features & Benefits​

1. Proportional Control:​
   • Provides continuous, stepless adjustment of flow based on an electrical input signal (typically 0–10 V or 4–20 mA). This allows for precise speed and flow control in hydraulic circuits.
2. Compact Cartridge Design:​
   • Engineered for easy installation into machined cavities of custom manifolds, saving space and reducing external piping. This enhances system reliability by minimizing potential leak points.
3. High Precision & Repeatability:​
   • Offers excellent linearity between input signal and output flow, ensuring consistent and repeatable performance in applications such as injection molding, presses, and material handling.
4. Direct-Acting, Electrically Driven Spool:​
   • Features an integrated proportional solenoid that directly positions the spool without the need for pilot stages, resulting in faster response times and simplified control.

5. Robust Construction:​
   • Built with high-grade materials to withstand demanding industrial environments. Suitable for use with common hydraulic fluids (mineral oils, synthetics) within specified pressure and temperature ranges.
6. Integrated Electronics (Optional/Configurable):​
   • The “/T1” designation typically indicates onboard electronics for signal amplification and closed-loop feedback. This enables direct connection to a standard analog controller, improving control accuracy and stability.
7. Flexible Application:​
   • Ideal for applications requiring variable flow control, such as:
     • Speed regulation in hydraulic motors and cylinders
     • Pressure and flow control in test stands
     • Process control in industrial machinery
