The NAF-Turnex is a pneumatic control valve actuator that is designed for both on/off and modulating control, and mounts directly to the NAF-Torex butterfly valve, NAF-Setball SF ball sector valve, NAF-Setball ball sector valve and NAF-Duball ball valve without the need for additional mounting brackets.

It is available in both double acting and single acting and has internal air passages which means there are no external pipes to get damaged. The optional air block connects the actuator to a direct mount NAF-D30 Intelligent Positioner so that external positioner piping that get so easily damaged are a thing of the past.

Piston rods are mounted in PTFE bearings to ensure smooth operation and a range of splined sleeves are available for various stem diameters to reduce stock holding. This maintenance free actuator can easily be changed from fail open to fail closed by changing the spring pack that pre-loaded and safely contained. Limit position adjustments are available in both directions of travel.

Special emergency equipment and manual overrides can be fitted in the event of a loss of compressed air. These actuators are standard stock items in South Africa.
