Festo
172959
On/off valve HEE-D-MIDI-24
The Festo 172959 is a 3/2-way, closed, monostable piston gate valve featuring electrical actuation and a piloted control type with soft sealing. Operating at a pressure range of 0.25 MPa to 1.6 MPa (2.5 bar to 16 bar), this component utilizes a mechanical spring reset method, a detenting manual override, and a positive overlap lap with a 100% duty cycle. The unit requires a 24 V DC, 2.5 W coil with permissible voltage fluctuations of +/- 10% and operates within medium and ambient temperature ranges of -10 °C to 60 °C using compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases.

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.
