Second, you need a check valve that is going to perform reliably and consistently between scheduled maintenance periods. The OPTI-MAX Cartridge Check Valve System from Optimize is designed to offer maximal performance and ease of use. A single OPTI-MAX cartridge is interchangeable across multiple pump brands, and will function in either the inlet or outlet position. The same cartridge will fit into pumps made by Shimadzu, Waters, Hitachi, and most other OEM solvent delivery systems, allowing you to minimize the number of spare check valve cartridges in your inventory. The performance of a check valve can only be as good as the integrity of the seal made between the ball and seat inside it.
Cartridges eliminate many components used in conventional check valves.
Interchangeable cartridges reduce inventory. Simple to use. Rebuild check valves by dropping a cartridge into the housing. One cartridge fits multiple brand housings. PEEK and SS cartridges are available in versions for standard, microbore and extended flow rate applications.
