Descripción completa del producto

The active operated 2-way servo proportional valves with VCD technology series TFP are outstandingly suitable for demanding applications where highest flows have to be controlled at maximum dynamics.

Thanks to the enormous flow rates combined with lowest pressure losses, they provide an almost unique energy density. This enables the use of smaller sizes and thus the design of size- and cost-optimized control manifold blocks. Moreover, the maximum performance is increasing. As a result, systems with significantly higher flow can be realized, e.g. with large die cast machines for the automotive industry.

The proportional cartridge throttle valves have a 2-stage design consisting of a DFplus pilot valve and a main stage with pressure-compensated poppet and LVDT. The optimized, patented sleeve allows the almost entire use of the ISO cavity, its oriented windows enable the optimum adaption of the control manifold block design.

With the DFplus pilot valve, the TFP achieves extremely fast response times: from 11 ms (NG25) up to 32 ms (NG100). The integrated electronics in the pilot valve has two control loops for main poppet and the pilot spool. The active control is positioning the main poppet independent of the pressure conditions occurring in the system.

Markets:
• Industrial
• Molding

Features/Benefits:
• Active operated 2-way servo proportional valve
• 7 sizes, NG25 up to NG100
• Cavity and mounting pattern according to ISO 7368
• Flow range up to 11100 l/min at 5 bar Δp
• Highest power density – saves typically one size when designing control manifold blocks and thus enables smaller blocks with the same performance
• High precision – for high quality products, minimum scrap rate and long machine lifetime
• Extremely fast step response – shortens material processing and thus cycle times
• 420 bar maximum operating pressure – increases performance in particularly demanding applications
• LVDT installed in the pilot chamber – protects from pressure peaks and thus increases reliability
• Short delivery time – no warehousing necessary
• Fail save position in case of electrical power down

Applications:
• Die cast
• General presses
• Injection molding

Please note:
For using the maximum TFP valve dynamics Parker recommends a minimum pilot pressure on the same level as the system pressure (max. 350 bar). Generally, a pilot pressure below 140 bar can affect the valve dynamics and lead to deviations from the specified data for step and frequency response.
