Valve Repair Kit is the box of parts we use to fix worn or leaking control valves. It usually has O-rings, spools, springs, backup rings and seals that fit main, pilot and spool valves. When a valve block leaks oil or acts sticky, we tear it down, clean the body and swap in fresh parts from the kit. That stops drips and brings back crisp control. We keep repair kits for each valve type, so we can service on site fast. Fix valves, keep work flowing.
