A customer using water presses in their facility was looking for a product that would increase the length between maintenance times on a cartridge, and lower the overall inventory cost.
The customer was changing out a conventional oil hydraulics counterbalance valve monthly. A lot of time was spent replacing the cartridges, and a sizable inventory was kept due to the high turnover rate of the components. The current part they were using was designed for use in a conventional oil hydraulics system, and did not stand up to the highly corrosive water environment.
Elwood was able to evaluate the existing system and design a custom stainless steel cartridge that fit into the existing cavity of the counterbalance valve. After testing, the components were able to extend the life of the cartridge exponentially and successfully decrease the amount of inventory needed to support the cartridges.
