Name: Festo 172963 On/off valve HEE-D-MAXI-110
Brand: Festo

On/off valve HEE-D-MAXI-110

The Festo 172963 is a 3/2-way closed, monostable industrial component featuring a piloted, electrically actuated piston gate valve design with a soft sealing principle and positive overlap lap. Operating across a pressure range of 0.25 MPa to 1.6 MPa (2.5 bar to 16 bar), this unit utilizes a mechanical spring reset method, a detenting manual override, and a 110 V AC 50/60 Hz coil with a 100% duty cycle. It functions with compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases within a medium and ambient temperature range of -10 °C to 60 °C, while offering moderate corrosion resistance (CRC 2) and 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.

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.
