Function and configuration
Valves of type 2WRCVE...-L1X/P... is a pilot proportional servo cartridge valve with valve core position feedback and integrated amplifier
Set-up:
They consist of the following assemblies:
Pilot servo valve with spool valve sleeve structure driven by voice coil valve.
Main valve with reset spring and position feedback.
Main valve displacement sensor and main valve integrated amplifier.
Function:
The 2-way servo proportional valves TDP have a 2-stage design consisting of a pilot valve and a main stage with poppet and LVDT.
Due to the use of a voice coil motor as the pilot valve, the TDP achieves extremely fast response times: from 17ms (NG63) up to 28ms (NG100) with an accuracy of <0.1% of the nominal flow.
The pilot valve actively controls the poppet - independent of the pressure conditions in the main ports. It is basically required that the pilot pressure is at the level of the system pressure. At low system pressure the pilot pressure should be min. 140bar, when high valve dynamics are desired.
The pilot servo valve and main valve of the valve are each equipped with an integrated amplifier with a closed-loop control circuit, which control the main valve and the pilot valve.

Installation recommendations
An insufficient pilot oil supply (e.g. due to long distances and/or small diameters) can negatively influence the dynamics of the valve.
To avoid this, an accumulator can be connected to port XX at the valve body. A short-term undersupply with pilot oil can be compensated via this accumulator.
