Cartridge valve TDP0 series

hydrauliccontrolpilot

The pilot operated 2-way high response valves series TDP provide a precise control of high flows at maximum dynamics. Typical applications for these slip-in cartridge proportional throttle valves are die cast, injection molding and hydraulic presses. Parker’s 2-way high response valves series TDP are particularly suitable for demanding controlled and closed loop applications where high flow has to be precisely controlled at highest dynamics. The proportional throttle valves have a 2-stage design consisting of a DFplus pilot valve and a main stage with poppet and LVDT. With the DFplus pilot valve the TDP achieves extremely fast response times: from 10.5 ms (NG25) up 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. The integrated electronics in the pilot of the TDP has two control loops for the main poppet and the pilot spool. Markets: • Industrial • Molding Features/Benefits: • High precision – for high quality products, minimum scrap rate and long machine lifetime • Extremely fast step response – shortens material processing and thus cycle times • Short delivery time – no warehousing necessary • Active pilot operated 2-way high-response valve • Cavity and mounting pattern according to ISO 7368 • Flow direction B to A and A to B • Completely mounted and adapted unit with integrated electronics • Fail save position in case of electrical and/or hydraulic power down • In order to ensure the closed position, pilot pressure is required. • 8 sizes NG25 up to NG100 Applications: • Die cast • General presses • Injection molding
