Name: Festo 172946 On/off valve HEE-1/2-D-MIDI-230
Brand: Festo

On/off valve HEE-1/2-D-MIDI-230

The Festo 172946 is an electrical piston gate valve featuring a soft sealing principle, positive overlap lap, and a 3/2-way, closed, monostable valve function with piloted control and a mechanical spring reset. Operating within a pressure range of 0.25 MPa to 1.6 MPa (2.5 bar to 16 bar), this 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, powered by a 230 V AC 50/60 Hz coil with a 100% duty cycle. It includes a detenting manual override, a non-throtttable exhaust air function, and moderate corrosion resistance (CRC 2), while accommodating compressed air to ISO 8573-1:2010 [7:4:4] or inert gases with oil lubrication permitted.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
