Spool valve NG10 with roller actuation WDTFA10
The existing roller valve has been equipped with a more robust actuating mechanism and the hydraulic peak performances have been increased. The valve can now switch a volume flow of 160 l/min at up to 350 bar. The actuation roller can also absorb higher transverse forces and is very well protected against contamination and corrosion. The direct operated valve of nominal size NG10 is available as a 4/2-way execution with the designation WDTFA10. This valve is used for applications in which electrical elements are consciously dispensed with or where a purely mechanical actuation is required.
Further details can be found in data sheet 1.5-56. The WDTFA10 can completely replace the AT4x10 predecessor valve. The dimensions and in particular the actuation dimensions of the roller are identical.
