Quarter turn actuator, single-acting, spring return, size 240, flange F0710 DFPD-240-RP-90-RS60-F0710-R3 - Festo 8048148

If the compressed air fails, the spring set of the DFPD-240-RP-90-RS60-F0710-R3 turns the valve into the defined position with at least 84 Nm spring torque. It mounts via the F0710 hole pattern to ISO 5211, the T22 shaft, depth 24 mm engages the valve stem.

Benefits

• 89.5 to 171.6 Nm with compressed air (6 bar) and 84 to 166.1 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 F0710, shaft connection T22
• Valve interface to VDI/VDE 3845 (NAMUR) for direct mounting of a solenoid valve, positioner and position sensor interface size AA 2
• For hazardous areas: ATEX II 2G and II 2D, ignition protection Ex h IIC T4 Gb X
• Air consumption 8.6 l per switching cycle at 6 bar

Applications

It operates 90-degree valves with top flange F0710, for example ball valves or butterfly valves in pipelines. Thanks to ATEX II 2G/2D, the size 240 DFPD may be used in zones 1 and 2 as well as zones 21 and 22. Medium: compressed air to ISO 8573-1:2010 [7:4:4], permitted 2 to 8 bar, rated at 6 bar. For sizing the valve bracket: product weight 10 kg.
