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.
