01 · The challenge
Harrow built its own valve blocks from machined bodies and bought-in seals, and a fifth of them leaked on the test rig.
02 · Our approach
We now machine the bodies, fit the seals and fittings, and pressure test every block at 350 bar before it is packed and labelled.
03 · The result
Harrow receives tested blocks on a weekly call-off. Scrap on their line is down by 40%, and they no longer stock loose parts.
“We stopped building valve blocks and started fitting them. That alone freed up two people on the line.”
Production Manager, Harrow Hydraulics
