Name: Festo 173900 On/off valve HEE-1/8-D-MINI-24-NPT
Brand: Festo

On/off valve HEE-1/8-D-MINI-24-NPT

The Festo 173900 is an electrically actuated piston gate valve featuring a 3/2-way, closed, monostable valve function with a 40 mm width dimension and soft sealing principle. Operating on compressed air according to ISO 8573-1:2010 [7:4:4] or inert gases within a pressure range of 0.25 MPa to 1.6 MPa, this piloted component delivers a normal nominal flow rate of 1000 l/min with a positive overlap lap, C value of 4.4 l/sbar, and b-value of 0.44. It includes a detenting manual override, mechanical spring reset, non-throttleable exhaust air function, 100% duty cycle, and a 24 V DC coil drawing 2.5 W with +/- 10% permissible voltage fluctuations under moderate corrosion stress (CRC 2).

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.
