Festo
172941
On/off valve HEE-3/8-D-MIDI-24
The Festo 172941 is a 3/2-way closed, monostable industrial component featuring an electrical piston gate valve design with piloted control, soft sealing principle, and positive overlap lap. Operating on a 24 V DC, 2.5 W coil with a 100% duty cycle and +/- 10% permissible voltage fluctuations, this unit handles an operating pressure range of 0.25 MPa to 1.6 MPa (2.5 bar to 16 bar) while delivering a normal nominal flow rate of 3200 l/min and a C value of 15.7 l/sbar. It incorporates a mechanical spring reset method, detenting manual override, and unthrottlable exhaust air function for use with compressed air per ISO 8573-1:2010 [7:4:4] or inert gases, permitting oil lubrication while maintaining a CRC 2 moderate corrosion resistance class and RoHS compliance.

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.
