Pressure Sequence Valve
Poppet Type, Direct-Acting
Metric Cartridge – 350 bar
DZ5E
Up to 20 l/min
Up to 350 bar
The pressure sequence valve DZ5E is a
direct-acting, spring-loaded poppet valve
with built-in check valve. In the normal
position, the path from port 1 to port 2 is
blocked.
If the pressure exceeds the pre-set
spring tension, the piston and poppet
move together in a closed condition
to the upper limit of the poppet. If
the pressure continues to rise, the
piston unblocks the path from 1 to 2
(consumer) so that oil can ow.
This opens the connection to the
additional consumers from port 2. In the
return direction from port 2 to 1, the main
piston is pushed back by the spring into
its initial position and the poppet opens
against the corresponding spring and
allows free ow from port 2 to port 1.
The spring chamber pressure is vented
to atmosphere.
FEATURES
z To connect additional consumers once certain pressures are reached
z To connect cylinders in sequence circuits
z As a pressure relief valve if free ow is required in the opposite direction
z Excellent dynamic performance
z Excellent stability throughout ow range
z Hardened and ground valve components to ensure minimal wear and extended
service life
z Adjustable throughout ow range
z Various pressure ranges up to 350 bar
z Optional zinc-plated version available
