Rexroth Core Series Part II: Motors and Directional Control Valves

Note on this series: This is the second in our Rexroth Core Series, spotlighting high-demand Rexroth components and how Hydraulic Parts Source (HPS) supports distributors, rebuilders, and service teams through core purchasing and supply. In Part 1, we discussed popular pump models like the A4V, A6, A10V, and SYDFE. Today, in Part 2, we cover motors like the A2F and directional control valves (DCVs) such as the 4WE6 and 4WE10. In Part 3, we’ll go deeper into our in-house repair capabilities for Rexroth piston pumps, and servicing models like the A4V, A6, and SYDFE.

When it comes to hydraulic systems in heavy equipment, Rexroth has long been a trusted name. Known for their engineering precision and durability, Rexroth motors and directional control valves are standard components from construction and agriculture to manufacturing and industrial machinery.

Due to growing demand, Hydraulics Parts Source not only offers Bosch-Rexroth’s popular A10VSO series piston pumps, but repair services on Proportional valves, and the SYDFEE series using the A10VSO DFEE proportional controls.

In this article, we’re breaking down motors such as the A2F series and directional control valves like the 4WE6 and 4WE10, which are not only in high demand but also offer strong opportunities for rebuild and resale. Here’s what you should know.

Rexroth A2F Motors: Dependable Power

The A2F axial piston fixed motor is a staple in many hydraulic systems. Known for its high-power density and compact design, the A2F motor is widely used in construction and agricultural equipment.

Because these motors are so widely used, there’s a constant need for rebuildable cores.

Distributors who can supply or exchange A2F cores provide a valuable service to contractors and fleet managers who can’t afford downtime.

By keeping A2F cores in circulation, you give your customers access to faster turnaround times and lower costs compared to sourcing new units.

Key Benefits of the A2F Motor:

• Robust design: Built for continuous operation under heavy loads.
• High efficiency: Delivers reliable torque and smooth operation.
• Versatility: Available in a wide range of displacements for various applications.
• Long service life: Engineered with precision manufacturing standards that stand up to demanding environments.

Rexroth Directional Control Valves: 4WE6 and 4WE10

Directional control valves are the workhorses of hydraulic circuits, directing fluid flow where it’s needed to power cylinders, motors, and actuators. Rexroth’s 4WE6 and 4WE10 series valves are industry standards for construction and industrial machinery.

Rexroth 4WE6 Valves

• Size 6 valve suitable for smaller systems with moderate flow requirements.
• Compact yet powerful, making it ideal for tight spaces and precision control.
• Common in mobile equipment where space and efficiency are key.

Rexroth 4WE10 Valves

• Size 10 valve designed for higher flow rates and larger systems.
• Built to handle heavy-duty applications such as excavators, loaders, and presses.
• Offers rugged reliability where durability is critical.

Why Cores Matter For DCVs

Like motors, these valves can be rebuilt to extend their life cycle. Cores for 4WE6 and 4WE10 valves allow distributors to support fast replacement needs while keeping overall costs in check. With many fleets running mixed or aging equipment, having rebuildable Rexroth cores available ensures you can service a wide range of customers.

Carrying Rexroth cores, whether for A2F motors or 4WE6/4WE10 directional control valves, offer several advantages:

• Faster lead times: Exchange cores keep your customers’ equipment running with minimal downtime.
• Stronger relationships: Supplying rebuildable cores demonstrates reliability and expertise.
• Revenue opportunities: Core purchasing and exchanges allow you to expand your offerings while maintaining competitive pricing.
• Market credibility: Aligning with Rexroth reinforces your reputation for quality parts.

Keep Rexroth Cores Stocked With HPS

Rexroth hydraulic components, particularly A2F motors and 4WE6/4WE10 directional control valves, are in constant demand across construction, agriculture, and industrial sectors. By purchasing and stocking Rexroth cores, distributors strengthen their ability to respond quickly, reduce downtime for customers, and ensure long-term value.

At Hydraulic Parts Source, we understand the importance of keeping Rexroth parts in circulation. Our team is here to help distributors secure the cores they need, whether it’s motors, valves, or other critical components, so you can continue delivering reliable solutions to your customers.
