Name: Festo 8211836 Quarter turn actuator DFPD-6500-SY-Y-90-RD-F1625
Brand: Festo

Quarter turn actuator DFPD-6500-SY-Y-90-RD-F1625

The Festo size 6500 industrial component, part number 8211836, features a double-acting kinematic yoke system with an F1625 flange hole pattern and a 90-degree swivel angle. Operating at a nominal pressure of 5.5 bar with an 18 bar burst pressure, this unit includes standard ISO 5211 valve connections, VDI/VDE 3845 NAMUR compliance, and an ATEX CE marking. Certified for safety functions up to SIL 2 in low demand mode and SIL 3 in redundant architecture pursuant to ISO 13849 and IEC 61508, the device supports any mounting position and features adjustable end-positions from -5 to 5 degrees at both 0 degrees and the nominal swivel angle.

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.

Safety function: The safety function consists of the actuator switching to the dened | safety switching position. This switching movement is achieved by | pressurizing the corresponding pressure chamber with compressed air. | The value of the torque generated depends on the pressure diﬀerence | between the two pressure chambers separated by the piston.
Safety integrity level (SIL): Up to SIL 2 low demand mode | up to SIL 3 in a redundant architecture
Certied for safety function to ISO 13849 and IEC 61508 (SIL): Product can be used in safety-related parts of control systems up to SIL | 2, low demand | up to SIL 3 in a redundant architecture
Burst pressure: 18 bar
Operating pressure: 0.3 MPa...0.6 MPa | 3 bar...6 bar | 43.5 psi...87 psi
Nominal operating pressure: 0.55 MPa | 5.5 bar | 79.75 psi
CE marking (see declaration of conformity): as per EU explosion protection directive (ATEX)
UKCA marking (see declaration of conformity): acc. to UK EX instructions
Explosion protection certication outside the EU: EPL Db (GB) | EPL Gb (GB)

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.
