Festo
8091771
On/off valve MS4-EE-1/4-V24-B
The Festo 8091771 is a size 4 industrial component from the MS series featuring a 40 mm width dimension and an electrically actuated poppet valve structural design. It incorporates a piloted control type, a 3/2-way closed monostable valve function with a negative overlap lap, and supports an operating pressure range of 0.3 MPa to 0.7 MPa (3 bar to 7 bar). Driven by a 24 V DC coil consuming 2.3 W with +/- 10% permissible voltage fluctuations, the unit achieves a normal nominal flow rate of 2000 l/min and an exhaust standard flow rate of 1600 l/min using compressed air according to ISO 8573-1:2010 [7:4:4].

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.
