Festo
173914
On/off valve HEE-1-D-MAXI-24-NPT
The Festo 173914 is an electrically actuated piston gate valve featuring a 3/2-way, closed, monostable valve function with a soft sealing principle and positive overlap lap. 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 6500 l/min, a C value of 27.6 l/sbar, and a b-value of 0.32 using compressed air or inert gases with a 100% duty cycle. The unit includes a 24 V DC, 2.5 W coil with +/- 10% permissible voltage fluctuations, a detenting manual override, a mechanical spring reset method, and a moderate corrosion resistance class (CRC 2) rating.

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.
