186516

On/off valve HEE-1/4-D-MIDI-230

The Festo 186516 is an electrically actuated 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 detenting manual override. Rated for an operating 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 2400 l/min, a C value of 7 l/sbar, and a b-value of 0.47, utilizing a 230 V AC (50/60 Hz) coil with 100% duty cycle and mechanical spring reset. It operates using compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases, permits oil lubrication, and exhibits a corrosion resistance class (CRC) of 2 alongside RoHS-compliant material construction.

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.
