Description
The single-acting DFPD in size 20 moves the valve with 7.6 to 14.7 Nm air torque at 6 bar and returns it by spring with 7.2 to 14.3 Nm. Flange pattern F03 to ISO 5211 and shaft connection T9, depth 10 mm fit directly onto the valve top.
Benefits
- 7.6 to 14.7 Nm with compressed air (6 bar) and 7.2 to 14.3 Nm from the spring set
- Safety position by spring force if air supply fails, device type to VDMA 66413: safety component
- Valve interface to ISO 5211: flange F03, shaft connection T9
- 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
- Suitable for safety-related control systems (SRP/CS) up to SIL 2 Low Demand
Applications
It operates 90-degree valves with top flange F03, for example ball valves or butterfly valves in pipelines. The ATEX rating II 2G/2D allows the DFPD-N-20-RP-90-RS60-F03-R3-EP to be installed in zones 1 and 2 as well as zones 21 and 22. The DFPD-N-20-RP-90-RS60-F03-R3-EP runs on compressed air to ISO 8573-1:2010 [7:4:4] within 2 to 8 bar. The product weight is 1.42 kg.
