Name: Festo 547019 Solenoid valve VSNB-FC-M52-M-G14-1A1-EX4A
Brand: Festo

Solenoid valve VSNB-FC-M52-M-G14-1A1-EX4A

The Festo 547019 is a 44.5 mm wide industrial component featuring a piston slide design structure with soft sealing and an 8 mm nominal size. This electrically actuated, piloted valve provides 5/2 and 3/2 monostable functions with a standard nominal flow rate of 950 l/min, mechanical spring reset, throttleable exhaust-air function, and freedom from overlap. Operating within a working and pilot pressure range of 2.5 to 8 bar, it conforms to the VDI/VDE 3845 NAMUR standard, offers IP65 protection, and achieves a 45 ms switch-on time and 165 ms switch-off time for any assembly 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. 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.
