PSV2-8 - Pressure Sequence Valve
Spool, direct acting normally closed, internal drain
23 L/min (6 USgpm) • 210 bar (3000 psi)
Operation
When a pre-set pilot pressure
is reached the spool moves
back against the spring
opening the line between inlet
and outlet.
When the pilot pressure falls
the valve will return to its
normal position.
Features
Cartridge design enabling
speedy servicing when
mounted in a body or in a
composite manifold.

Description
This valve provides a means of
opening a pressure line when
a predetermined pilot pressure
is reached in a normally closed
form.
The valve can be used in any
pilot or small flow system as a
remotely operated sequence
valve.
