Description

With up to 842 Nm at 5.5 bar nominal pressure, the size 900 DFPD operates ball valves and butterfly valves with flange pattern F14. It mounts via the F14 hole pattern to ISO 5211, the T36 shaft, depth 38 mm engages the valve stem.

Benefits

842 Nm torque across the 90° swivel angle at 5.5 bar
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
Suitable for safety-related control systems (SRP/CS) up to SIL 2 Low Demand
Shaft made of high-alloy stainless steel, ambient temperature -20 to 80 °C

Applications

Typical tasks are on/off actuation of ball valves, butterfly valves and plug valves with top flange F14. 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-RD-F14-R3-EP runs on compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar. The product weight is 25.6 kg.
