New IQ valve actuator has optimised stem acceptance and torque output
Rotork has introduced a new model in its IQ range of nonintrusive intelligent electric actuators with an optimised combination of valve stem diameter acceptance and torque output to facilitate economical automation of valves and penstocks typically found in the water and eff luent treatment industries.
The new IQ19 actuator combines a stem acceptance of up to 51mm diameter with torque output up to 135 Nm and output speeds up to 72 rpm. The combination meets the operating requirements of large numbers of penstocks, sluice gates and gate valves.
The actuator incorporates the f ull range of advanced reliability, f unctionality and asset management features, including an unrivalled range of data logging capabilities, for which the Rotork IQ marque is well known.
Reliability is optimised by the IQ double-sealed IP66/IP68 watertight and temporarily submersible enclosure, which permanently protects internal electrics from the ambient environment, even during site wiring with the terminal housing cover removed.
