Parker Series TDC 2-Way High Performance Proportional Throttle Valve

Parker’s 2-way high performance proportional throttle valves series TDC are particularly suitable for demanding controlled applications where high flow has to be precisely controlled at high dynamics.

These slip-in cartridge valves have a 2-stage design consisting of a proportional pilot valve and a main stage with poppet and LVDT. With the pilot valve the TDC achieves fast response times: from 20 ms (NG25) up to 31 ms (NG50) with an accuracy of <0.7 % of the nominal flow. The pilot valve actively controls the poppet – independent of the pressure conditions in the main ports.

Markets:

• Industrial
• Molding
