Parker's 2-way high response valves series TDP are paticularly suitable for demanding controlled and closed loop applications wherehigh flow has to be precisely controlled at highest dynamics.
The proportional throtle valves have a 2-stage design consisting of a DFplus pilot valve and a main stage with poppet and LVoT. With theDFplus pilot valve the TDP achieves extremely fast response times,from 10,5 ms (NG25) uo to 28 ms (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. Theintegrated electronics in the pilot of the TDP has two control loops for the main poppet and the pilot spool.
