Description
The double-acting DFPD-N-480-RP-90-RD-F1012-R3-EP turns process valves in both directions with compressed air and delivers 474 Nm at 5.5 bar. Flange pattern F1012 to ISO 5211 and shaft connection T27, depth 29 mm fit directly onto the valve top.
Benefits
- Torque 474 Nm at 5.5 bar nominal pressure
- Valve interface to ISO 5211: flange F1012, shaft connection T27
- 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 40.5 l per switching cycle at 6 bar
- End position at 0° adjustable by -5 to 5°
Applications
The DFPD is intended for quarter-turn valves with top flange F1012, such as ball valves and butterfly valves in process plants. The ATEX rating II 2G/2D allows the DFPD-N-480-RP-90-RD-F1012-R3-EP 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 2 to 8 bar, nominal pressure 5.5 bar. For sizing the valve bracket: product weight 16 kg.
