DESCRIPTION OF FUNCTION, SECTION
8
The stroke of the poppet (3) at the internal diameter is
limited by the spring retainer (2). The built-in spring (4)
supports the closing movement and also serves to hold
the valve poppet (3) in the closed position.
The slip-in cartridge (5) can be inverted in its bore,
enabling simple field changes from free flow IN to free
flow OUT, and vice versa. The flow direction is marked
on the cartridge with a check valve symbol.
Check valves type N-ZREP06 are direct operated valves
in sandwich plate design. They give leakfree closure in
one direction and allow free flow in the other.
