Stackable Directional Control Valve SystemStackable Directional
Control Valve SystemThe TDV100 is a closed center, load sensing,
sectional control valve with pre-compensation. The TDV100 can be
confi gured with 1 to 10 working sections and can be used with fi
xed displacement or with pressure/fl ow compensated variable
displacement pumps.
When multiple functions are selected, the TDV100 will
automatically resolve the highest function load pressure which is
then transmitted to the pump or inlet unloader/by-pass compensator
and drained to tank once all spools are returned to neutral.
Each TDV100 sectional valve is crossed by a pilot pressure
supply line and a return rail to feed 16-20 bar to the MULTIDROM*
electro-hydraulic actuators system.
