Brand: Festo

Semi-rotary drive DFPD-1200-RP-90-RS55-F1012

The Festo 8151232 industrial component features a size 1200 single-acting gear rack and pinion valve actuator with an ISO 5211 standard connection, an F1012 flange hole pattern, and a 90-degree swivel angle. Operating at a nominal pressure of 5.5 bar (79.75 psi) with an operating range of 2 bar to 8 bar and a burst pressure of 24 bar, this safety device includes a spring assembly that switches the actuator to a defined safety switching position when compressed air is removed and the spring chamber is exhausted. It is certified to ISO 13849 and IEC 61508 for use in safety-related control systems up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture, featuring VDI/VDE 3845 NAMUR valve connections and VDI/VDE 3845 Size AA 3 connection points for positioners and sensors.

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.
