APPLICATION
Wanduh poppet valves can be used any-
where absolutely leak tight closing functions
are important. Completely sealed loading,
gripping and clamping operations are all
important functions which Wanduh poppet
valves can perform. Cartridge type poppet
valves can be neatly accommodated in valve
blocks. From a mechanical and functional
point of view, poppet valves can replace slide
valves at any time.
DESCRIPTION
Poppet valve, anged design NG6 according
to ISO 4401, available as a 2/2 or 3/2-way val -
ve (normally open or c losed) and as a 3/4-way
valve (normally closed). The central functio-
ning element of all directly controlled poppoet
valves in the NG6 series is the poppet valve
cartridge NG6. See data sheet 1.11-2030.

FUNCTION
The valve is direct operated by a hydraulic
control head which either opens or closes
the poppet against a spr ing. The design of the
poppet spool, which is equal in sur face area on
both sides and thus pressure balanced, means
there are no undue opening and closing hy-
draulic forces. Due to this the oil ow through
the poppet valve is possible in both directions.
The valve is tight in both ow directions.
