Quarter turn actuator, single-acting, spring return, size 40, flange F0507 DFPD-40-RP-90-RS60-F0507-R3-EP - Festo 8047630

If the compressed air fails, the spring set of the DFPD-40-RP-90-RS60-F0507-R3-EP turns the valve into the defined position with at least 13.8 Nm spring torque. It mounts via the F0507 hole pattern to ISO 5211, the T14 shaft, depth 16 mm engages the valve stem.

Benefits

• 14.5 to 28 Nm with compressed air (6 bar) and 13.8 to 27.2 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 T14
• 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
• Air consumption 1.5 l per switching cycle at 6 bar

Applications
