Check Valve Housing Selection Here is a partial listing of check valve housings (with cartridge included) for most pumps. If you do not see your pump vendor listed, please contact us. We have many other check valves for other pumps as well. After the initial purchase of the housing and check valve, you need only purchase replacement check valve cartridges. And you may use the same cartridge for different pumps if compatible. You can also try different cartridge types to see what works best for your pump. The list below does not include ruby ball and sapphire seats check valve cartridges. If you would prefer ruby balls and sapphire seats, just change the part number as follows: AB-XY-CDEF where Y is a 7 or a 9. 7 denotes ruby ball and sapphire seat in a stainless steel cartridge. 9 denotes ruby ball and sapphire seat in a PEEK cartridge. X denotes the diameter of the ball and can be 4, 5 or 6. If you need assistance, please contact us. We are happy to assist you.
