TCW Technologies has introduced a control valve servo kit, which includes a small linear actuator, a panel-mounted controller and a pre-made wiring harness. The CVS kit can be used in homebuilt aircraft to control dampers and valves for heat and ventilation. The system replaces traditional mechanical push-pull cables and eliminates the routing and locating issues associated with mechanical cables. The linear actuator weighs only 1.2 ounces and produces more than 2.5 pounds of force. Additionally, 3-inch- and 4-inch-diameter butterfly valves are available for controlling the airflow through oil coilers. The CVS kit sells for $175 and the butterfly valves are $65 each.
