Pneumatic rotary actuator, spring closing, flange F10 (square 27), size 90

As a rotary actuator the article operates valves with compressed air through the square of the drive shaft. This version comes with size 90, a spring closing design and square drive 22 mm. It is complemented by a torque of 257 Nm at 10 bar. Also stated are mounting flange F10 (square 27).

Benefits

• Torque of 257 Nm at 6 bar and 257 Nm at 10 bar.
• Mounting flange F10 (square 27) to ISO 5211 for direct mounting on the valve.
• Drive connection with a polygon to DIN 3337, square drive 22 mm.
• Interface for a solenoid valve, a positioner or a limit switch box to VDI/VDE 3845, interface 130 x 30.
• Design spring closing with air connection G 1/4" and a position indicator to NAMUR.

Applications

In process engineering the actuator switches ball valves and butterfly valves with a torque of 257 Nm at 6 bar.

Standards and conformity

The mounting flange follows ISO 5211, the drive connection DIN 3337 and the interfaces for solenoid valve and positioner VDI/VDE 3845.
