Description

With up to 20.1 Nm at 5.5 bar nominal pressure, the size 20 DFPD operates ball valves and butterfly valves with flange pattern F03. It mounts via the F03 hole pattern to ISO 5211, the T9 shaft, depth 10 mm engages the valve stem.

Benefits

  • Torque 20.1 Nm at 5.5 bar nominal pressure
  • 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
  • Suitable for safety-related control systems (SRP/CS) up to SIL 2 Low Demand
  • Air consumption 1.8 l per switching cycle at 6 bar

Applications

It operates 90-degree valves with top flange F03, for example ball valves or butterfly valves in pipelines. ATEX category II 2G/2D permits use of the DFPD-20 in zones 1 and 2 as well as zones 21 and 22. Medium: compressed air to ISO 8573-1:2010 [7:4:4], permitted 2 to 8 bar, rated at 5.5 bar. The product weight is 1.27 kg.
