The SD10120 is a ow control valve
which controls the ow rate by means
of an adjustable cross section. The ow
rate depends on the pressure differential
and the viscosity. Starting with the throttle
spindle in the fully closed position when
the ow is shut off, the ow rate increases
in accordance with the appropriate curve
as the control knob is turned. The ow is
controlled in both directions. The scale
and coloured scale rings on the top of
the control knob enable accurate repeat
setting.
General
z For regulating the speed of loads
z For ne adjustment and shut-off of the ow
z For system-related damping in hydraulic circuits
z Patented safety mechanism prevents spindle from working loose
z A set-screw locks the setting
z All valve parts made of high-strength steel with hardened and ground components
to ensure minimal wear and extended service life
z Optional zinc-plated version available
