Every Repair Includes
Every valve that comes through our shop is fully disassembled, cleaned, and inspected against OEM specifications. We test motor torque response, spool travel, internal leakage, and null bias on dedicated test benches before any repair begins; then we rebuild, recalibrate, and burn-in test the completed unit for 12 to 24 hours to confirm it performs under real-world conditions before it ships back to you.
