4543

Name: Festo 4543 Air solenoid valve MOFH-3-M5
Brand: Festo

Air solenoid valve MOFH-3-M5

The Festo 4543 is a directly controlled industrial component featuring a 3/2-way monostable open valve function with a plate seat structural design and soft sealing principle. This electrically actuated part operates within a pressure range of 0 bar to 6.5 bar (0 MPa to 0.65 MPa), delivering a normal nominal flow rate of 46 l/min through an M5 pneumatic working port with a nominal width of 1.5 mm. Equipped with a mechanical spring reset, detenting manual override, and non-reversible flow direction, the unit achieves an on switching time of 12 ms and an off switching time of 8.5 ms using compressed air per ISO 8573-1:2010 [7:4:4] with optional oil lubrication. The assembly holds c UL us recognition and VDMA24364-B2-L LABS conformity while supporting installation in any mounting position.

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.

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.
