TDC050ES99C2NE063 PROP. 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

Features/Benefits:
• Robust valve design – ensures high reliability
• High precision and repeatability – for high quality products, minimum scrap rate and long machine lifetime
• Fast step response – shortens material processing and thus cycle times
• Active pilot operated 2-way high performance 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
• 4 sizes NG25 up to NG50
• Short delivery time – no warehousing necessary

Applications:
• General presses
• Injection molding

Please note:
In order to ensure the closed position, pilot pressure is required. 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. 140 bar, when high valve dynamics are desired.
