Pressure sequence valve type UZKB 6 serves to control
pressure in hydraulic systems. It can be well used as a
direct operated pressure relief valve.

OPERATION DESCRIPTION

Spring force is adjusted by turning the handwheel ( 6 ) of
the setting element. If control pressure overcomes the resistance of the spring ( 3 ), the control spool ( 2 ) moves and
opens the connection P to P1.

The spool ( 2 ) in the housing ( 1 ) is pressure-loaded from
port P and from opposite side spring ( 3 ) - loaded in relation
to the spring deflection.
