Quarter turn actuator, single-acting, spring return, size 20, flange F05 DFPD-20-RP-90-RS60-F05-R3-EP - Festo 8048017

If the compressed air fails, the spring set of the DFPD-20-RP-90-RS60-F05-R3-EP turns the valve into the defined position with at least 7.2 Nm spring torque. It mounts via the F05 hole pattern to ISO 5211, the T11 shaft, depth 12 mm engages the valve stem.

Benefits

• 7.6 to 14.7 Nm with compressed air (6 bar) and 7.2 to 14.3 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 F05, shaft connection T11
• 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 0.8 l per switching cycle at 6 bar

Applications

Typical tasks are on/off actuation of ball valves, butterfly valves and plug valves with top flange F05. ATEX category II 2G/2D permits use of the DFPD-20 in zones 1 and 2 as well as zones 21 and 22. The DFPD-20-RP-90-RS60-F05-R3-EP runs on compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar. The product weight is 1.42 kg.
