AdvantagesWater Ingress Protected O-Rings are fitted on bodies, caps andso on,this ensure water ingress protected.

The NSF Series actuators interfacemeets ISO standard,and meets thedimensional requirements of ISOdefined for each torque range.

StandardizationThe shaft driven accessory interfaceconforms to NAMUR and is identical on allNSF Series models, allowing standardizationof accessory mounting hardware and installation practices.

Wear Resistant The guide rod and piston rod have anadvanced surface treatment, whichcombined with self-lubricating bearings, provides superior wear resistance andextends the life of all sliding components.

Corrosion Resistant The NSF series actuators incorporate

over three stages of internal andexternal coatings to resist severeweather,chemical and petroleumenvironments. The inner surface ofcylinder is coated by PTFE, enhancedcorrosion resistant and self-lubricating

NSF series actuators have available, field-serviceable drive, power, spring and override modules, the modules are removable, serviceable and interchangeable whenmounted to the valve. Modules are available for seperated purchase to reduce spare partsinventory

Safe Spring Module To ensure the safety of personnel during installation and maintenance, the spring module has been designed so that it can only be removed from the power module with the spring in the fully extended position. This prevents accidental release of the spring force, protecting personnel from injury and the actuator from accidental damage.

General ApplicationTorque Outputs(guaranteed)Double acting: 302~226,400NmSpring return end torques: 187~71753Nm

Operating PressuresPneumatic: 3~7 BarHydraulic: 100 Bar (Over 100bar hydraulic pressure is available upon request)

Operating Temperatures:Standard: -20°C~80°CLow Temperature: -40°C~80°CHigh Temperature: -20°C~150°C

Design Features Offer Unique Benefits1 Safe Spring LockPositively locks the spring modulein place under load. This prevents springmodule detachment from the drivemodule.

Connects the piston rod with theguide block, compensating forside load deflection and reducingwear on rod, bearings and seals.
