Festo
1246073
Semi-rotary actuator DFPB-20-090-S6-F04
This Festo industrial component features a size 20 rack and pinion design structure with a single-acting mode of operation and a 90-degree swivel angle without cushioning. Built with an F04 flange hole pattern and a NAMUR valve connection based on VDI/VDE 3845, it operates at a nominal working pressure of 5.6 bar and maximum working pressures up to 8 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4]. The unit provides SIL 3 Low Demand mode safety integrity and ATEX certification for hazardous environments, maintaining an ambient and explosion-proof temperature range of -20°C to +80°C in any assembly position.

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.
