Description

If the compressed air fails, the spring set of the DFPD-160-RP-90-RS35-F07-R3-C-VDE2 turns the valve into the defined position with at least 33.7 Nm spring torque. Mounting is via flange F07 (ISO 5211) and shaft connection T22, depth 24 mm.

Benefits

  • Air torque 35.8 to 68.8 Nm at 3.5 bar, spring return torque 33.7 to 66.6 Nm
  • Safety position by spring force if air supply fails, device type to VDMA 66413: safety component
  • Valve interface to ISO 5211: flange F07, shaft connection T22
  • 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 5.9 l per switching cycle at 6 bar

Applications

The DFPD is intended for quarter-turn valves with top flange F07, such as ball valves and butterfly valves in process plants. ATEX category II 2G/2D permits use of the DFPD-160 in zones 1 and 2 as well as zones 21 and 22. The DFPD-160-RP-90-RS35-F07-R3-C-VDE2 runs on compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar. The product weight is 6.85 kg.
