Independent Third-Party Valve Repair Specialists Since 1975
Pegasus Servo Valve Repair & Sales
NC Servo Technology is an independent repair facility specializing in Pegasus servo valves. We operate 13 dedicated in-house test stands, maintain a large rebuilt inventory ready to ship, and back every repair with a 1-year warranty.
Whether your line is down or you need a tested replacement unit fast, we can help — without the lead times or minimum orders of an OEM program.
Third-Party Service Overview
Independent Pegasus Valve Repair — Built Around Your Uptime
NC Servo is not a Pegasus-authorized facility. We are an independent repair shop with 50 years of experience servicing hydraulic servo valves — including discontinued and hard-to-find Pegasus models. Every unit is evaluated, cleaned, and tested to performance standards before leaving our bench.
Disassembly & Evaluation
Ultrasonic cleaning, component inspection, and bench testing on every unit before it ships.
Exchange & Sales Options
Our 19,000-unit inventory includes rebuilt Pegasus valves available for purchase. Exchange and core credit options may be available based on your unit's condition.
Documentation Options
Repair notes and test summaries are available to help document service results as needed.
Testing & Diagnostics
13 Test Stands. Every Valve Tested Before It Ships.
Our test stands are configured to reproduce the duty cycles these valves see in the field — injection molding presses, industrial presses, and hydraulic positioning systems. Each Pegasus unit is tested for flow, leakage, and gain before it leaves our bench.
- 13 hydraulic and electronic test stands validate flow, leakage, and gain prior to shipment.
- Closed-loop verification confirms performance across temperature and pressure setpoints.
- Optional performance curves and test graphs available for purchase with any repair.
- Pegasus valves spanning the 10 through 180 series are tested on stands configured for their flow range.
Inventory & Exchange
Large Rebuilt Inventory — Ready to Ship
We stock a large inventory of rebuilt Pegasus servo valves and process cores directly in-house. When your line is down, you don't have time for distributor lead times — we ship on your schedule.
Expedited Allocation
When stock and scheduling allow, units can be allocated on an expedited basis to support urgent requests.
Core Processing
Returned cores are inspected and processed according to standard procedures to keep replacements moving.
Discontinued Pegasus Support
Many Pegasus valve models are no longer in production. Our inventory includes discontinued units cataloged, cleaned, and staged to keep older machinery running.
Quality Assurance
Every Repair Leaves Our Bench — Not the OEM's
We stand behind our own work with a 1-year warranty on every repair. Parts are sourced from our large in-house valve inventory — primarily OEM components pulled from donor units — supplemented with quality aftermarket parts where needed.
- Seals, elastomers, and internal components sourced from OEM stock where available.
- Aftermarket parts used when OEM components are unavailable or discontinued.
- Flow and leakage checked before the unit ships — results on file.
- NC Servo's 1-year warranty applies regardless of the valve's age or OEM support status.
Who We Serve
Independent Pegasus Valve Service Across Every Industry
Maintenance managers and plant engineers across plastics, steel, and heavy industry send us Pegasus valves when the OEM can't deliver fast enough — or when the model has been discontinued entirely.
Injection Molding
Pegasus valves are found in older injection molding machines where fast, reliable replacement keeps cycle times on target.
Industrial Presses
Hydraulic press applications rely on Pegasus valves for positioning and force control. We keep these systems running with tested replacements.
Heavy Manufacturing
Steel mills, forming equipment, and heavy machinery with legacy Pegasus valves get responsive, tested replacements from our inventory.
