Festo
173908
On/off valve HEE-1/2-D-MIDI-24-NPT
The Festo 173908 is an electrical piston gate valve featuring a 3/2-way, closed, monostable valve function with a positive overlap lap and soft sealing principle. Operating at pressures from 0.25 MPa to 1.6 MPa (2.5 bar to 16 bar), this piloted component delivers a normal nominal flow rate of 3600 l/min with a C value of 17 l/sbar and a b-value of 0.3. It incorporates a 24 V DC, 2.5 W coil with 100% duty cycle, mechanical spring reset, detenting manual override, and a width dimension of 55 mm within a corrosion resistance class 2 housing.

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.
