Description
The double-acting actuator DAPS-1440-090-R-F12 turns quarter-turn valves through 90° and delivers 1440 Nm at the start position at 5.6 bar nominal pressure. The valve mounts directly via flange F12 to ISO 5211 and shaft connection T36.
Benefits
- Torque at 5.6 bar: 1440 Nm at 0°, 720 Nm at 50°, 1080 Nm at 90°
- Flange hole pattern F12 to ISO 5211, shaft connection T36 with 38.5 mm depth
- NAMUR valve interface to VDI/VDE 3845 for direct mounting of a solenoid valve
- ATEX II 2G and II 2D, type of protection Ex h IIC T6...T3 Gb X
- Usable in SRP/CS up to SIL 2, low demand and high demand
- Corrosion resistance class 3, ambient temperature -20 to 80 °C
Applications
The DAPS-1440-090-R-F12 sits on water, wastewater and process valves with flange F12. It works at 1 to 8.4 bar and uses 53.2 l of air per switching cycle at 6 bar.
