1DS60 - Pressure Sequence Valve
Spool. direct acting, normally closed, internal pilot, external drain
60 L/min (16 USgpm) • 40 bar (580 psi)
Description
Direct acting sequence
valves are ideal for diverting
oil to a second circuit at a
predetermined pressure as in
clamp and drill circuits, or as a
relief where the back pressure
varies. By taking the drain line
directly to tank, back pressure
effects are negated.
Operation
As with the direct acting relief
valves, when the pressure
exceeds the spring force, the
spool moves back, opening the
inlet to outlet.
Features
Stable, quiet operation.
Cartridge construction
gives maximum flexibility
in mounting. Offering good
repeatability and reseat.
