High flow cartridge valves type SHLI, SHLIR
Directional control, optional poppet seal, ISO 7368 sizes 16÷50

SHLI* are 2 way cartridge valves, with
high flow performances and low pressure
drops.
The high flow capability of SHLI* permits
to reduce the cartridge size in comparison with standard SC LI, see section ݚ
and consequently a reduction of the overall block dimensions.
The recess dimensions conform to ISO
7368 standard.
They can be used with all standard Atos
covers to realize directional controls, see
tab. H030 and H040.
Two different execution are available:
- SHLI, high flow cartridges without poppet seal.
- SHLIR, as SHLI, but with special LAP
dynamic poppet seal to avoid internal
leakages from B to X piloting line, for
applications requiring improved leakfree feature.
