Description
The 2-way/2-position solenoid-operated directional
seat valves, series WR22_Z..., are size 5, two stage,
pressure balanced screw-in valves with an M20x1,5
mounting thread. The main and pilot stages are both
designed on the poppet/seat principle, and the 1 to 2
ow path is therefore virtually leak-free. The straight-
forward design delivers a good price/performance ra-
tio and outstanding head loss/ ow ratings. All exter-
nal parts of the screw-in valves are zinc-nickel plated,
and are thus suitable for use in the harshest opera-
ting environments. The slip-on coils can be replaced
without opening the hydraulic envelope and can be
positioned at any angle through 360°. These valves
are primarily used as pilot valves in certain mobile
and industrial applications where leak-tight shut-o
functions are crucially important. Examples are where
loads, tensions, or clamping forces must be held wi-
thout leakage. For self-assembly, please refer to the
section related data sheets.
