Festo
542578
On/off valve MS4-EE-1/4-10V24
The Festo 542578 is a 3/2-way closed, monostable industrial component featuring a piloted, electrically actuated piston gate valve with a non-detenting manual override and mechanical spring reset. Operating at pressures from 4 bar to 10 bar, this unit delivers a normal nominal flow rate of 2000 l/min, a C value of 9.5 l/sbar, a b-value of 0.44, and a positive overlap lap with an unthrottleable exhaust air function. Designed for a 100% duty cycle using 24 V DC (1.8 W) coil characteristics, it functions within a medium temperature range of -10 °C to 50 °C with compressed air per ISO 8573-1:2010 [7:4:4] or inert gases, where oil lubrication is possible and required for continued operation. The assembly provides moderate corrosion stress resistance (CRC 2), VDMA24364-B1/B2-L LABS conformity, and RoHS-compliant materials.

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.
