Inspection and Repair Process

Each OLSEN D7R-8-60-240-S undergoes reconditioning — disassembly, parts replacement, reassembly, and bench testing before shipment.

About This Unit

We handle a wide range of OLSEN D7R-8-60-240-S units. Each one receives inspection, internal cleaning, and reconditioning before it ships.

Frequently Asked Questions

Yes. Our technicians can often identify units based on photos, dimensions, or manufacturer markings. Send a photo before shipping to speed up intake.

Send the unit in whatever condition it’s in. We clean everything during teardown before inspection begins.

Helpful but not required. If you can photograph the label, connectors, and overall unit, it gives our team a head start.

If the main housing or board is intact, repair is usually the better option. We can restore most units to working condition with tested parts.

It depends on the unit and scope of work. We provide an estimated timeline after initial evaluation.

Independent Repair Facility

Disassembly and Rebuild Procedure

Our team disassembles each valve to assess internal wear. After ultrasonic cleaning, we install replacements and reassemble and verify operation.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.

Hydraulic Testing Process

We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing. Our test facility supports performance logging and report generation. Our operational testing verifies consistent performance.
