Shut-off valve VBOC-L2-E-S7-P-M12-G38-E

The Festo 8177445 is a pneumatic 2/2-way closed, monostable industrial component featuring G3/8 pneumatic connections and an integrated exhaust air one-way flow control function with manual exhaust capability. This welding spatter-resistant part operates within a 0.5 bar to 10 bar pressure range, delivering a standardized nominal flow rate of 430 l/min in the flow control direction and 640 l/min to 730 l/min in the non-return direction using compressed air according to ISO 8573-1:2010 [7:4:4]. It is equipped with a sealing ring on the screwed plug, a detenting manual override, and complies with EU and UK EMC and RoHS directives for installation in any mounting position between -5 °C and 60 °C.

Why no listed price?

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.
