Festo
153479
Shut-off valve HE-3-1/8-QS-6
The Festo 153479 is a directly controlled 3/2-way bistable industrial component featuring a piston gate valve structural design with a soft sealing principle and non-reversible flow direction. Built with a reinforced PBT housing, this manual-actuated unit delivers a normal nominal flow rate of 279.9 l/min through an R1/8 pneumatic connection 1 and a QS-6 pneumatic connection 2, operating within a pressure range of -0.95 bar to 10 bar. It includes an unthrottled exhaust function, accommodates direct mounting via through-hole or thread in any mounting position, and is rated for a moderate corrosion resistance class of 2 with compressed air media in temperatures from 0 °C to 60 °C.

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.
