PSV3-10 - Pressure Sequence Valve
Spool, direct acting, normally closed, internal or external pilot/drain
23 L/min (6 USgpm) • 210 bar (3000 psi)
Operation
The valve is normally closed
until a pre-determined pressure
is applied to port 1. The spool
then shifts and allows flow
from port 1 to port 2.
When port 3 is pressurized the
spool shifts to allow flow from
port 2 to port 1.
Features
Stable, quiet operation.
Cartridge construction
gives maximum flexibility
in mounting. Offering good
repeatability and reseat.
Performance DataSectional View
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.
Pressurizing port 3 will allow
free flow from port 2 to port 1.
