VALVE PLATE-L - A7VO250

The Valve Plate - L is a precision-engineered replacement spare part for Bosch Rexroth A7VO250 series axial piston variable pumps, compatible with the left-hand rotation variant. Ideal for high-pressure systems, this hydraulic component features kidney-shaped ports and durable alloy steel construction for optimal performance and longevity.

Technical Details

• Compatibility: Fits Bosch Rexroth A7VO250 axial piston variable pumps with bent-axis tapered piston design.
• Rotation: Left-hand (L) for precise fluid intake and discharge orientation.
• Pressure Rating: Handles up to 350 bar nominal (peak 400 bar) in demanding hydraulic applications.
• Displacement/Flow: Supports 250 cm³/rev variable displacement, with flow rates up to 500 L/min.
• Material: High-wear-resistant metal with machined ports, relief grooves, and damping features for low noise and minimal leakage.
• Dimensions: Typically 150-200 mm diameter, 20-30 mm thick, optimized for efficiency.

Applications

Essential for heavy-duty hydraulic systems in construction equipment like excavators and loaders, agricultural machinery such as tractors, industrial presses, mining operations, forestry tools, marine hydraulics, and material handling like cranes.

Purpose

This Bosch Rexroth A7VO250 valve plate regulates hydraulic fluid intake and discharge, dividing suction and pressure sides for smooth piston operation. It reduces friction via a lubricating film, minimizes energy loss, and enables variable displacement control. Perfect for pump repairs to restore efficiency, prevent leaks, and extend system life in hydraulic pump maintenance.
