Brand: Festo

Quarter turn actuator DFPD-1200-RP-90-RS60-F1012

The Festo part number 8084143 is a single-acting industrial component featuring a gear rack and pinion structural design with a valve actuator size of 1200 and a 90-degree swivel angle. Operating at a nominal pressure of 0.6 MPa, 6 bar, or 87 psi with an operating pressure range of 2 bar to 8 bar, this safety device achieves its safety function via spring force when compressed air is switched off and the spring chamber is exhausted. It includes an ISO 5211 standard connection for valves, an F1012 flange hole pattern, a 29 mm shaft connection depth, and VDI/VDE 3845 compliance for NAMUR valve connections and positioner mounting. Certified for safety functions up to SIL 2 in low demand mode and SIL 1 in high demand mode according to ISO 13849 and IEC 61508, the unit functions in any mounting position with a burst pressure of 24 bar.

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.

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.
