Festo
543543
Regulator plate VABF-S3-1-R5C2-C-10
The Festo 543543 is an industrial component designed with a width of 26 mm based on the ISO 15407-1 norm, featuring pneumatic vertical stacking for a reversible pressure regulator for ports 2 and 4. It delivers a constant output pressure with secondary exhausting across a pressure regulation range of 0.05 MPa to 0.85 MPa (0.5 bar to 8.5 bar, or 7.25 psi to 123.25 psi) and supports an inlet pressure 1 from 0.5 bar to 10 bar using compressed air as per ISO 8573-1:2010 [7:4:4]. Weighing 430 g with an IP65 and NEMA 4 degree of protection, this unit mounts in any position on a manifold sub-base or individual sub-base and accommodates an optional pressure gauge with a retaining clamp.

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.
