NELES ACTUATOR TYPE F1 –
The Neles rack and pinion type actuator is designedto be used in demanding high cycle applications.Due to the working principle the actuator has acompact and symmetrical design allowing easyattachments of valves and accessories based onISO5211, Namur and VDI/VDE3845 standards. Thetorque range cover torques from 30 Nm to25 000 Nm for maximum supply pressure of 10bars1) and it it is suitable to be used with all kind ofrotary valves. If a failure mode is required, the spring returnType F1F series should be selected. The actuator canbe equipped with a spring to close or with a springto open system. The operating torque can bemodified with the amount of springs to be used.
FEATURES
Versatility□ Modular designs with same body and mounting con-
nections for double-acting and spring-return reducethe inventory. Springs can be added in the field toincrease the torque requirement.
□ To change the function of spring-to-close can be easilyconverted in the field to spring-to-open system.
□ Actuator to valve attachments comply with ISO 5211/1and EN 12116.
□ Solenoid valve and accessory attachments complywith NAMUR VDI/VDE 3845.
□ A wide range of optional accessories and controldevices that include limit switches, solenoid valves andmechanical safety lockouts are available to satisfy vir-tually all automated valve requirements.
High life cycle □ Bearings on all sliding and rotating moving parts
ensure long life. The actuator is greased for life toexpand the already long life time even more.
□ Option of ideally formed dual pistons to minimize thedead air volume. This increases the operation speedand makes the actuator pneumatically stiffer improv-ing the control capabilities.
□ Hard-anodized extruded aluminum body with honedinternal surface for strength and lower coefficient offriction.
□ Machined teeth on piston racks and pinions for excel-lent rack and pinion engagement and maximum effi-ciency.
□ Extended temperature range option decreases cyclelife.

NELES DUAL PISTON TURN ACTUATORSNeles rack and pinnion actuators have a proven record of successin control and safety drive applications. They are especially usedfor high safety specifications. Neles dual piston actuators work“stick-slip” free and manage a high number of turnings evenunder extreme climatic and operating conditions.Rugged design coupled with adequate spare capacity, togetherwith the use of tried and tested materials guarantee high loadcycling life and high reliability.On the double-acting turn actuator Type F1A both pistonsreceive pressure via the outer chambers in moving towards eachother or via the inner chamber in moving away from each other.
Axial movement of the pistons is transmitted via the gearing tothe drive shaft.On the single-acting actuator Type F1F drive shaft movementresults from both pistons receiving pressure to move away fromeach other or on a pressure drop by springs causing the pistonsto move towards each other.It is also possible to operate a single acting actuator Type F1Fwith air to open and closing (spring is only for fail position).

Options:□ Manual over ride
Declutchable manual overrideA side-declutchable manual override is available for Neles TypeF1A and F1F actuators. It consists of a manual gear actuatormounted between the actuator and the valve. The device is nor-mally disengaged from the shaft. Upon engagemant of the over-ride clutch, overriding the actuator is done with ease, aided bythe high-reduction ratio of the manual gear unit.
Example for a standard single acting actuator F1A, size 120, outside stoke limitation, square profile connection , 10 springs, double action spring support to close operation.
