172940

On/off valve HEE-3/8-D-MINI-230

The Festo 172940 is an electrically actuated piston gate valve featuring a soft sealing principle, piloted control, and a 3/2-way closed monostable valve function with a positive overlap lap. Operating on a 230 V AC (50/60 Hz) coil with a 100% duty cycle, this component handles an operating pressure range of 0.25 MPa to 1.6 MPa and achieves a normal nominal flow rate of 1600 l/min for compressed air or inert gases. It incorporates a mechanical spring reset method, detenting manual override, non-throttleable exhaust air function, and a moderate corrosion resistance class (CRC 2) with RoHS-compliant materials.

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.

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.
