Brand: Festo

Semi-rotary drive DFPD-40-RP-90-RS55-F04

The Festo industrial component 8071605 is a single-acting gear rack and pinion valve actuator of size 40 with a 90-degree swivel angle and an ISO 5211 standard valve connection. Certified for safety functions to ISO 13849 and IEC 61508, this safety device operates at a nominal pressure of 5.5 bar (79.75 psi) and supports safety integrity levels up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture. The safety function relies on spring force to switch the actuator to a defined position when compressed air is switched off and the spring chamber is exhausted.

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.
