Description

The double-acting DFPD-N-20-RP-90-RD-F05 turns process valves in both directions with compressed air and delivers 20.1 Nm at 5.5 bar. It mounts via the F05 hole pattern to ISO 5211, the T11 shaft, depth 12 mm engages the valve stem.

Benefits

  • Torque 20.1 Nm at 5.5 bar nominal pressure
  • 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
  • End position at 0° adjustable by -5 to 5°
  • Suitable for safety-related control systems (SRP/CS) up to SIL 2 Low Demand

Applications

Typical tasks are on/off actuation of ball valves, butterfly valves and plug valves with top flange F05. 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 1.27 kg.
