Name: Festo 541281 On/off valve MS4N-EM1-1/4-S
Brand: Festo

On/off valve MS4N-EM1-1/4-S

The Festo 541281 is a rotary vane industrial component featuring a direct, manually actuated 3/2-way bistable valve function with an unthrottlable exhaust air function. It operates within a pressure range of 0 MPa to 1.4 MPa (0 bar to 14 bar) and delivers a normal nominal flow rate of 2200 l/min, utilizing compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases with a C value of 9 l/sbar and b-value of 0.39. Constructed with a moderate corrosion resistance class (CRC 2) and RoHS-compliant materials supporting oil-lubricated operation, this non-reversible unit functions within a temperature range of -10 °C to 60 °C and accommodates in-line installation or mounting with accessories in any position.

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.
