About Series 300
Versatile! Interchangeable! Flexible Configurations! Our most popular series allows you to mix and match end fittings (barbed, NPT, and foot valve styles) to create the ideal valve for your low pressure, low flow project. You may also use the same configuration on both ends. Internally, modular solutions incorporate check valve cartridge model #150 or #160 to eliminate leak prone adapter by combining end fittings and check valve into one part. For pump applications, Model #315 (foot/filtering valve) is easily paired with any Series 300 end fitting. At Smart Products USA, all of our valves are customizable by plastic body material, o-ring material, and opening spring pressure to meet specific application criteria.
