Festo
543603
Throttle plate VABF-S3-2-F1B1-C
The Festo 543603 is an industrial component designed for pneumatic vertical stacking with exhaust air flow control via a throttle plate, featuring an 18 mm width and an operating pressure range of -0.9 bar to 10 bar based on the ISO 15407-1 norm. Housed in die-cast aluminum with a product weight of 228 g, it offers IP65 and NEMA 4 degrees of protection, a corrosion resistance class of CRC 0, and mounts flexibly on a manifold sub-base or individual sub-base in any mounting position using compressed air as per ISO 8573-1:2010 [7:4:4]. This RoHS-compliant RoHS unit operates within ambient temperatures from -5 °C to 50 °C and permits oil lubrication for continued operation while conforming to VDMA24364-B1/B2-L LABS standards.

Request a QuoteWhy 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.
