Fast, Reliable Rexroth and Proportional Valve Repairs to Get Your Client Running

Did you know Hydraulic Parts Source offers OE-quality remanufactured A10VSO series piston pumps from Rexroth, along with servo and proportional valve repair services and a wide selection of replacement parts?

Well, we do — and more importantly, we do it fast and right.

As your trusted problem-solving supplier, HPS is proud to deliver quick-turnaround repair and remanufacturing services that help you avoid costly downtime and keep your hydraulic systems running at peak performance.

Whether you're dealing with a failed pump, an aging proportional valve, or a discontinued part, our goal is simple: Get you a reliable replacement — fast.

We know you need a working unit in your hands ASAP, and you need it to work right. So, we’ll help you by replacing it with a remanufactured part that we already have in stock, but if it's not, we'll repair your unit to like-new, OE-standard quality with a lightning-fast turnaround.

When You Need It Fixed Right — Right Now

We know the pressure you're under. When a Rexroth pump or valve goes down, you're not just dealing with a component issue — you're dealing with lost production, missed deadlines, and frustrated customers. And when you need a fix, you don’t have time to wait weeks for OEM lead times or for someone to “figure it out.”

That’s where HPS shines.

We specialize in A10VSO series pump repairs and proportional valve rebuilding — two of the most common trouble spots in high-performance hydraulic systems.

These are complex components that require deep technical knowledge, precision equipment, and real OE-standard processes. That’s exactly what we bring to the table.

Proportional Valve Repair: Bring Precision Back to Your System

Servo and proportional valves are the heart of modern, high-precision hydraulic control systems—but they’re also prone to failure due to contamination, wear, or electronic malfunction.

At HPS, we don’t just clean and reseal — we fully restore these sensitive components to OEM-like conditions.

What We Do:

• Cleanroom-level disassembly and inspection
• Replacement of coils, spools, electronics, and seals as needed
• Dynamic bench testing for flow and electrical function
• Zero-leak and deadband verification for optimal performance
• Detailed service reports available on request

Proportional Valves We Commonly Service:

• Rexroth/Bosch proportional and servo valves
• Vickers/Eaton valves including KDG4V, KFDG5V series
• Moog servo valves
• Parker/Dennison electro-hydraulic valves
• Atos, Tokimec, and other major brands

Our process ensures the unit you receive performs like new, saving you and your customer thousands over the replacement cost, and getting your system back online sooner.
