Name: Festo 186518 On/off valve HEE-1/2-D-MAXI-24
Brand: Festo

On/off valve HEE-1/2-D-MAXI-24

The Festo 186518 is an electrical piston gate valve featuring a 3/2-way, closed, monostable valve function with piloted control and a soft sealing principle. It delivers a normal nominal flow rate of 5600 l/min at a C value of 24.2 l/sbar and a b-value of 0.3, operating within a pressure range of 0.25 MPa to 1.6 MPa using compressed air or inert gases. Equipped with a detenting manual override, mechanical spring reset, and a 24 V DC, 2.5 W coil with a 100% duty cycle, this RoHS-compliant component exhibits a moderate corrosion stress rating and supports oil-lubricated operation.

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.
