Quarter turn actuator, single-acting, spring return, size 120, flange F0507 DFPD-120-RP-90-RS30-F0507 - Festo 8048133

If the compressed air fails, the spring set of the DFPD-120-RP-90-RS30-F0507 turns the valve into the defined position with at least 21.1 Nm spring torque. It mounts via the F0507 hole pattern to ISO 5211, the T17 shaft, depth 19 mm engages the valve stem.

Benefits

• 22.4 to 43 Nm with compressed air (3 bar) and 21.1 to 41.6 Nm from the spring set
• Safety position by spring force if air supply fails, operating pressure 2 to 8 bar
• Valve interface to ISO 5211: flange F0507, shaft connection T17
• Valve interface to VDI/VDE 3845 (NAMUR) for direct mounting of a solenoid valve, positioner and position sensor interface size AA 1
• For hazardous areas: ATEX II 2G and II 2D, ignition protection Ex h IIC T4 Gb X
• Suitable for safety-related control systems (SRP/CS) up to SIL 2 High Demand

Applications

Typical tasks are on/off actuation of ball valves, butterfly valves and plug valves with top flange F0507.
