Quarter turn actuator, single-acting, spring return, size 0480, flange F10/F12 DAPS-0480-090-RS4-F1012-MW - Festo 8005056

If the compressed air fails, the spring set of the DAPS-0480-090-RS4-F1012-MW turns the valve into the defined position with at least 240 Nm spring torque. It mounts via the F10/F12 hole pattern to ISO 5211, the T36 shaft, depth 38.5 mm engages the valve stem.

Benefits

• Air torque 240 to 480 Nm at 5.6 bar, spring return torque 240 to 480 Nm
• Safety position by spring force if air supply fails, operating pressure 5.6 to 8.4 bar
• Valve interface to ISO 5211: flange F10/F12, shaft connection T36
• 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 19.6 l per switching cycle at 6 bar

Applications

The DAPS is intended for quarter-turn valves with top flange F10/F12, such as ball valves and butterfly valves in process plants. The ATEX rating II 2G/2D allows the DAPS-0480-090-RS4-F1012-MW to be installed 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 5.6 to 8.4 bar, nominal pressure 5.6 bar. For sizing the valve bracket: product weight 28.1 kg.
