Description

With up to 3229 Nm at 5.5 bar nominal pressure, the size 3500 DFPD operates ball valves and butterfly valves with flange pattern F16. It mounts via the F16 hole pattern to ISO 5211, the T46 shaft, depth 50 mm engages the valve stem.

Benefits

Torque 3229 Nm at 5.5 bar nominal pressure
Valve interface to ISO 5211: flange F16, shaft connection T46
Valve interface to VDI/VDE 3845 (NAMUR) for direct mounting of a solenoid valve, positioner and position sensor interface size AA 3
For hazardous areas: ATEX II 2G and II 2D, ignition protection Ex h IIC T6 Gb
End position at 0° adjustable by -5 to 5°
Suitable for safety-related control systems (SRP/CS) up to SIL 2 Low Demand

Applications

The DFPD is intended for quarter-turn valves with top flange F16, such as ball valves and butterfly valves in process plants. For hazardous areas: the actuator with flange F16 is rated ATEX II 2G/2D for zones 1 and 2 as well as zones 21 and 22. The operating medium is compressed air to ISO 8573-1:2010 [7:3:4] within 2 to 6.8 bar, nominal pressure 5.5 bar. The product weight is 75.5 kg.
