Festo
6686
Air solenoid valve BMCH-2-3-1/8
The Festo 6686 is a directly controlled electrical industrial component featuring a 2x3/2 closed, monostable valve function with a mechanical spring reset method and a soft sealing principle. This poppet valve operates within a pressure range of -0.095 MPa to 0.7 MPa, delivers a normal nominal flow rate of 160 l/min through a G1/8 pneumatic working port, and requires 30 W for pick-up and 22 W for holding power consumption. Designed with an IP65 degree of protection, a 2.5 mm nominal width, and a product weight of 680 g, it functions with compressed air under ISO 8573-1:2010 [7:4:4] standards where oil lubrication is possible.

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
