Modular check valve NS 6 - Sandwich plate design for use in vertical stacking assemblies - Poppet design - Leakfree closure in one or two service ports - 8 different models - Installation dimensions to ISO 4401/ DN 24 340 Functional Description The check valve sandwich plates are used to allow flow in one direction and prevent flow in the other one. The sandwich design enables vertical stacking with other components of the same size. The check elements can be built into one or two ports, the other ports being Through-holes. The seat (3) is machined directly in the housing (1) and the poppet (2) is pushed onto the seat by compression spring (4). The cracking pressure depends on the spring used, on its preload and on the pressurized poppet surface area. The valve housing surface is phosphate coated.
