Hydraulic Pump DFR1 Control Valve for A10VSO16/18/28/45/63/71/85/100

Product Overview

The DFR1 Control Valve belongs to high‑quality Hydraulic Pump Spare Parts, specially designed for A10VSO16/18/28/45/63/71/85/100 series Hydraulic piston pump. Mounted on the main body of the hydraulic pump, it integrates pressure and flow composite control functions, effectively stabilizes the power output of the whole hydraulic system. This component is widely used for equipment overhaul and replacement in engineering machinery and industrial hydraulic stations.

Technical Specifications

- Product: DFR1 Control Valve

- Fit Models: A10VSO16, A10VSO18, A10VSO28, A10VSO45, A10VSO63, A10VSO71, A10VSO85, A10VSO100

- Matched equipment: Variable displacement Hydraulic piston pump

- Control mode: DFR1 pressure‑flow load‑sensing combined control

- Adapted medium: Anti‑wear hydraulic oil for hydraulic system

- Installation: Directly assembled on hydraulic pump housing

- Usage scenario: Repair & replacement as Hydraulic Pump Spare Parts

Working Principle

As the core regulating part of A10VSO series Hydraulic piston pump, the DFR1 Control Valve senses pressure and load signals from the hydraulic system, then adjusts the swashplate angle of the hydraulic pump. It realizes automatic flow limitation and pressure cutoff. When working load fluctuates, the valve responds rapidly to change pump displacement, reduce power waste and heat generation. These Hydraulic Pump Spare Parts can restore original pump performance when old control valve gets worn or fails.

Core Advantages

1. Good compatibility, suitable for full range A10VSO series Hydraulic piston pump, easy direct onsite replacement.

2. DFR1 integrated composite control, excellent response speed and high control precision for the hydraulic system.

3. Optimize power matching, lower energy consumption and reduce over‑heating risk of the hydraulic pump.

4. Compact structure, simple disassembly and maintenance; reliable performance under harsh working conditions.

5. Cost‑effective aftermarket Hydraulic Pump Spare Parts for pump repair.

Application Range

Widely applied in excavators, injection molding machines, hydraulic power units, material handling machinery and other heavy‑duty devices. This DFR1 Control Valve is one of the commonly‑used Hydraulic Pump Spare Parts, perfectly matching A10VSO series hydraulic pump, ensuring stable and efficient operation of the complete hydraulic system.
