Festo
541270
On/off valve MS6-EM1-1/2-Z
The Festo 541270 is a rotary vane industrial component featuring a manual, directly controlled 3/2-way bistable valve function with a non-reversible flow direction and an exhaust air function that cannot be throttled. It operates within a pressure range of 0 bar to 18 bar, delivers a normal nominal flow rate of 8700 l/min, and functions with compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases within a medium and ambient temperature range of -10 °C to 60 °C. Designed with a corrosion resistance class of 2 for moderate stress, RoHS compliance, and VDMA24364-B1/B2-L LABS conformity, it supports oil lubrication and can be mounted in any position either in-line or with accessories.

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.
