Description

For on/off valves with a safety position: the DFPD-N-900-RP-90-RS60-F14-R3-EP is single-acting with spring return and reaches up to 593.5 Nm at 6 bar. Flange pattern F14 to ISO 5211 and shaft connection T36, depth 38 mm fit directly onto the valve top.

Benefits

Air torque 323.6 to 593.5 Nm at 6 bar, spring return torque 325.1 to 595 Nm
Safety position by spring force if air supply fails, device type to VDMA 66413: safety component
Valve interface to ISO 5211: flange F14, shaft connection T36
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 T4 Gb X
Air consumption 31.5 l per switching cycle at 6 bar

Applications

The DFPD is intended for quarter-turn valves with top flange F14, such as ball valves and butterfly valves in process plants. Thanks to ATEX II 2G/2D, the size 900 DFPD may be used in zones 1 and 2 as well as zones 21 and 22. The DFPD-N-900-RP-90-RS60-F14-R3-EP runs on compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar. For sizing the valve bracket: product weight 30.4 kg.
