TCW Control Valve Servo Kit
Overview
|
The TCW Control Valve Servo Kit is a system for controlling valves and dampers such as those used to select cabin heat or ventilation or control air flow through oil coolers or radiators. The CVS kit includes an instrument panel mounted controller, a travel linear actuator servo and a pre-made 5-foot wiring harness. The controller provides fully proportional operation of the linear actuator servo, allowing the motion of the attached valve or damper to be selected at any position from fully opened to fully closed. Additionally, the CVS system may be coupled to an optional butterfly valve (3 or 4 available) for controlling the flow of cooling air through an oil cooler assembly. The standard kit includes a 1.2 oz Servo with a 30 mm travel linear actuator servo and a pre-made 5-foot wiring harness. The Heavy-Duty kit includes a 1.4 oz Servo with a 50 mm travel linear actuator servo and pre-made 5-foot wiring harness. The Standard Kit should be used with Vans RV Heater Valves and TCW butterfly valves. |

Installed but still in the build stage so it will be a year before I fly. They work well. I’m just concerned about the long term use as they will be exposed to vibration and heat mounted on the firewall. Time will tell. A lot of money for what you get.

Documentation is lacking for oil cooler butterfly valve. Figures in instruction only show heater box. Wiring connectors will have to be removed if your routing thru firewall. Would be better if supplied harness came with connectors not installed.

No, it cannot operate two actuators at once.
Per the manufacturer: The controller provides fully proportional operation of the linear actuator servo, allowing the motion of the attached valve or damper to be selected at any position from fully opened to fully closed.
