Festo
3410683
Hand lever valve VHER-P-H-B43U-M5
The Festo 3410683 is a 37 mm wide, directly controlled 4/3-way manual industrial component featuring a rotary vane structural design with a nominal width of 4 mm and a normal nominal flow rate of 170 l/min. Designed with a hard sealing principle and adjustable exhaust air function, this non-reversible valve operates within a 0 bar to 10 bar pressure range, supporting vacuum operation at connection 3 and dual pressure modes where port 1 pressure exceeds port 3. It is rated for ATEX Zone 2 and Zone 22 hazardous areas, utilizes ISO 8573-1:2010 [7:4:4] compressed air, and permits oil lubrication.

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.
