PSV8-10 - Pressure Sequence Valve
Spool direct acting, normally open, external 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 closing
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.
Performance DataSectional View
Description
This valve provides a means
of interrupting a pressure
line when a predetermined
pilot pressure is reached in a
normally open form.
The valve can be used in any
pilot or small flow system as a
remotely operated sequence
valve.
