Functional Description
The check valves sandwich plate are used to allow flow
in one direction and prevent flow in the other in the port
in which the check element is installed. The sandwich
design enables stacking with other components of the
same size. The check elements are build 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 the compression spring
(4). The cracking pressure depends on the spring
selected and the pressurised poppet surface area.
The valve housing surface is phosphate coated.
