541283

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

The Festo 541283 is a directly controlled, bistable 3/2-way rotary vane industrial component featuring manual actuation and a non-throttled 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 for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. The unit offers a C value of 9 l/sbar, a b-value of 0.39, moderate corrosion resistance (CRC 2), and accommodates a medium and ambient temperature range of -10 °C to 60 °C with optional in-line or accessory mounting 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
