Festo
8102818
Quarter turn actuator DFPD-120-RP-90-RS35-F07-R3-C
The Festo 8102818 is a single-acting gear rack and pinion industrial valve actuator featuring a size 120 body, an F07 flange hole pattern, and a nominal swivel angle of 90 degrees with an end-position adjusting range of -5 to 5 degrees at both 0 degrees and the nominal angle. Built with a shaft connection depth of 19 mm, an ISO 5211 standard valve connection, and VDI/VDE 3845 NAMUR and AA 1 compliance for positioners and sensors, it operates at a nominal pressure of 3.5 bar (50.75 psi) within an operating pressure range of 2 bar to 8 bar and a burst pressure of 24 bar. Certified as a safety device to ISO 13849 and IEC 61508 for SIL 2 low demand, SIL 1 high demand, and SIL 3 in redundant architectures, the unit performs its safety function by switching to the defined safety position via spring force when compressed air is switched off and the spring chamber is exhausted.

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.
