Festo
3520389
Hand lever valve VHER-H-B43C-B-N14
The Festo 3520389 is a manual 56 mm wide rotary vane industrial component featuring a direct 4/3-way closed valve function, an 8 mm nominal width, and a normal nominal flow rate of 1500 l/min at working ports with NPT1/4-18 threads. Operating at pressures from 0 bar to 10 bar, this unit supports vacuum operation exclusively at connection 3 and requires higher pressure at port 1 than at port 3 during dual pressure mode. Built with a hard sealing principle, non-reversible flow direction, adjustable exhaust air function, and underlap, it utilizes compressed air matching ISO 8573-1:2010 [7:4:4] and features CRC 2 moderate corrosion resistance with VDMA24364-B1/B2-L LABS conformity.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
