Quarter turn actuator, single-acting, spring return, size 0120, flange F05/F07 DAPS-0120-090-RS1-F0507-CR - Festo 552887

If the compressed air fails, the spring set of the DAPS-0120-090-RS1-F0507-CR turns the valve into the defined position with 30 to 60 Nm spring return torque. Mounting is via flange F05/F07 (ISO 5211) and shaft connection T17, depth 19.3 mm.

Benefits

• Spring return torque 30 to 60 Nm
• Safety position by spring force if air supply fails, operating pressure 2.8 to 8.4 bar
• Valve interface to ISO 5211: flange F05/F07, shaft connection T17
• Valve interface to VDI/VDE 3845 (NAMUR) for direct mounting of a solenoid valve
• For hazardous areas: ATEX II 2G and II 2D, ignition protection Ex h IIC T6...T3 Gb X
• Air consumption 4.9 l per switching cycle at 6 bar

Applications

It operates 90-degree valves with top flange F05/F07, for example ball valves or butterfly valves in pipelines. Thanks to ATEX II 2G/2D, the size 0120 DAPS may be used in zones 1 and 2 as well as zones 21 and 22. The operating medium is compressed air to ISO 8573-1:2010 [7:4:4] within 2.8 to 8.4 bar, nominal pressure 5.6 bar. For sizing the valve bracket: product weight 7.6 kg.
