Festo
172944
On/off valve HEE-1/2-D-MIDI-24
The Festo 172944 is an electrically actuated piston gate valve featuring a soft sealing principle and a 3/2-way, closed, monostable valve function with a 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 3600 l/min, a C value of 17 l/sbar, and a b-value of 0.3 using a 24 V DC, 2.5 W coil with 100% duty cycle. It utilizes mechanical spring reset, detenting manual override, and non-throttlable exhaust air, requiring compressed air per ISO 8573-1:2010 [7:4:4] or inert gases with optional oil lubrication, while offering a moderate corrosion resistance class (CRC 2) 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.
