PURETORQ invented and patented its vane-type, fixed seal, rotary pneumatic actuator, recognizing the need for long lasting, quarter-turn valve actuation with 11.30~768.33 Nm (100~6800 in-lbs) double acting torque output while the single acting torque output reaches 5.20~272.64 Nm (46~2413 in-lbs). Dual ISO/VDI VDE mounting pads and female drives efficiently facilitate the assembly with valves.

- Independent dual ISO patterns with corresponding female star shape drive on each actuator, i.e. F03/F04 on the VDA100 and VDA200. F04/F05 on VDA400, F05/F07 on VDA700, F07/F10 on VDA1600, F10/F12 on VDA3800 and F12/F14 on VDA6800.Double NAMUR VDI/VDE3845 mounting
- Standard interface for limit switches and positioners. Integrated shaft & vane
- The shaft and vane are virtually one unit with zero mechanical hysteresisRotary to rotary operation
- :All the torque is delivered directly to the valve, no loss due to friction or translation of linear motion into rotary motion.
- External spring return unit
- Less than 10% torque decay over 90 degree operation.
Certificate
- ISO 9001; PED 97/23/EC
