Festo
172949
On/off valve HEE-3/4-D-MIDI-230
The Festo 172949 is an electrical piston gate valve featuring a 3/2-way, closed, monostable valve function with piloted control and a soft sealing principle. It operates within a pressure range of 0.25 MPa to 1.6 MPa, delivers a normal nominal flow rate of 3800 l/min, and utilizes a 230 V AC coil with 100% duty cycle. This RoHS-compliant component includes a mechanical spring reset, detenting manual override, and positive overlap lap while requiring compressed air per ISO 8573-1:2010 [7:4:4] or inert gases with oil lubrication capability.

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.
