Festo
547021
Basic valve VSNB-F-M52-M-G14-P2
The Festo part number 547021 is a 5/2 monostable industrial component featuring a 44.5 mm width, a piston slide design structure, and a standard nominal flow rate of 950 l/min conforming to the VDI/VDE 3845 (NAMUR) standard. Operating within a working and pilot pressure range of 2.5 to 8 bar, this unit incorporates a mechanical spring reset, soft sealing principle, throttleable exhaust-air function, and freedom from overlap with a 100% duty cycle. It utilizes compressed air matching ISO8573-1:2010 [7:4:4] as an operating medium, allows for subsequently required lubricated operation, achieves a CRC corrosion resistance classification of 2, and features a nominal size of 8 mm with switching times of 30 ms on and 100 ms off in any assembly position.
