On/off valve MS6N-EM1-1/2-S-Z

The Festo 541291 is a directly controlled, manual rotary vane industrial component featuring a 3/2-way bistable valve function with non-throttlable exhaust air and a non-reversible flow direction. Operating within a pressure range of 0 bar to 18 bar, it delivers a normal nominal flow rate of 8700 l/min, a C value of 30.8 l/sbar, and a b-value of 0.57 for compressed air per ISO 8573-1:2010 [7:4:4] or inert gases. The unit offers moderate corrosion resistance (CRC 2), RoHS compliance, VDMA24364-B1/B2-L LABS conformity, and supports a medium and ambient temperature range of -10 °C to 60 °C with required oil lubrication.

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. 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.
