557631

Semi-rotary actuator DFPB-330-090-S5-F1012

The Festo size 330 single-acting rack and pinion industrial component features an F1012 flange hole pattern, a 90-degree swivel angle, and operates without cushioning in any assembly position up to 8 bar working pressure with a nominal pressure of 5.6 bar. This unit includes a NAMUR-conforming valve connection based on VDI/VDE 3845, utilizes compressed air per ISO8573-1:2010 [7:4:4] with lubricated operation possible, and delivers SIL ratings up to SIL 3 in Low Demand mode. Certified with II 2G c T4 X and II 2D c 125°C X ATEX classifications, the device functions within an ambient temperature range of -20°C to 80°C and an explosion-proof ambient temperature range of -20°C ≤ Ta ≤ +80°C without position detection capabilities.

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.
