Turnex

The Flowserve NAF Turnex is a heavy-duty actuator designed for high-performance modulating control. Since its introduction in the 1980s, it has demonstrated reliable, maintenance-free operation. Featuring a robust linkage system with bushing, it ensures an optimal torque curve for quarter-turn valves and eliminates play.

The Turnex actuator integrates seamlessly into the NAF control valve package with a unique direct mounting concept. It also supports on/off service with adjustable end-stops in both directions, and its consistent spare parts system, combined with a unique sleeve system for different stem diameters, minimizes the number of required spare parts.
