Electric Actuator Selected for Field Trials

The first five HBGVs are in production and the search for a multi-turn actuator lead us to the Indelac LA7B-12MVQ-MT. For the rigorous field tests expected this fall, we specified an actuator that was robust, fast, accurate and easy to commission. The selected actuator is a multi-turn device, 115 VAC powered with 4-20 mA input, 2000 lb-in output and continuous duty cycle. Applied to the HBGV, the actuator can respond to a command for a 5% change in restriction in less than 7 seconds.
