Located below the Electronic Draft Control valve (Where the Hydraulic Power T apping port (Power Beyond) includes a priority valve and also a low pressure regulating valve (1) This block also has a flange plate which allows the addition a trailer brake

Closed Centre Load Sensing High Pressure Hydraulic Circuit
The principal operation the closed centre load sensing high pressure hydraulic circuit with variable flow piston pump supply oil flow also enables simultaneous operation the trailer hydraulic remote control valve assemblies and front axle suspension where The load sensing variable flow piston pump fers significant benefits reducing the engine power loss that occurs open centre systems where a high volume oil, often far excess demand, continuously pumped round the hydraulic circuit even when they are not being
A fixed displacement pump (Charge Pump) serves initial displacement pump for the variable displacement pump The variable displacement pump first all supplies oil the trailer brake valve (where the remote valves and electronic draft control valve and a pilot oil supply with lower priority The highest load pressure indicated the flow and compensating valve the pump via the load sensing line. The flow and compensator valve controls the pump pressure such a way that always exceeds the highest load pressure a pre - set dif A priority valve for low pressure circuit demand located the bottom subplate the remote valve T ractors fitted with Electro - hydraulic remote valves also have high pressure oil supplied from the variable displacement pump the top plate the remote valve The oil passes through the top plate via a small filter and a pressure limiting valve ( - Bar The oil then directed the pilot oil supply the electro - hydraulic control
