Festo
153478
Shut-off valve HE-3-QS-12
The Festo 153478 is a bistable 3/2-way industrial component utilizing a piston gate valve structural design with direct control and a non-reversible flow direction. Featuring QS-12 pneumatic connections for both ports 1 and 2, this manually actuated valve delivers a normal nominal flow rate of 788.4 l/min at a nominal width of 4.7 mm across an operating pressure range of -0.95 bar to 10 bar. Constructed with a PBT-reinforced housing and soft sealing principle, the unit supports direct mounting via through-hole or in-line installation in any mounting position while operating on compressed air meeting ISO 8573-1:2010 [7:-:-] standards with a moderate corrosion resistance class of CRC 2.

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.
