Description
Double-acting quarter turn actuator with rack and pinion for quarter-turn valves: 234.3 Nm torque at 5.5 bar, swivel angle 90°. It mounts via the F0710 hole pattern to ISO 5211, the T22 shaft, depth 24 mm engages the valve stem.
Benefits
- Torque 234.3 Nm at 5.5 bar nominal pressure
- Valve interface to ISO 5211: flange F0710, shaft connection T22
- Valve interface to VDI/VDE 3845 (NAMUR) for direct mounting of a solenoid valve, positioner and position sensor interface size AA 2
- 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
The DFPD is intended for quarter-turn valves with top flange F0710, such as ball valves and butterfly valves in process plants. Thanks to ATEX II 2G/2D, the size 240 DFPD may be used in zones 1 and 2 as well as zones 21 and 22. The operating medium is compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar, nominal pressure 5.5 bar. The product weight is 8.59 kg.
