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.
