Description

If the compressed air fails, the spring set of the DFPD-20-RP-90-RS55-F03 turns the valve into the defined position with at least 6.6 Nm spring torque. It mounts via the F03 hole pattern to ISO 5211, the T9 shaft, depth 10 mm engages the valve stem.

Benefits

  • 7 to 13.5 Nm with compressed air (5.5 bar) and 6.6 to 13.1 Nm from the spring set
  • Safety position by spring force if air supply fails, device type to VDMA 66413: safety component
  • Valve interface to ISO 5211: flange F03, shaft connection T9
  • 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 F03. Thanks to ATEX II 2G/2D, the size 20 DFPD may be used in zones 1 and 2 as well as zones 21 and 22. The size 20 DFPD is supplied with compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar. The product weight is 1.41 kg.
