NORBRO high performance actuators

Since the mid-Sixties the Norbro name has been recognised as the leading quarter turn actuator for industry. As proof of this, Norbro pneumatic actuators can be found in a range of applications as diverse as the petrochemical industry, food and beverage, steel production, pharmaceuticals, plastics manufacturing and oil and gas.
From the very beginning Norbro has been dedicated to providing high performance actuators which combine reliability, long life and ease of maintenance with operational safety and a modular design concept which allows simple attachment of a variety of ancillaries to match customers requirements.

NORBRO Serie 40R

Applications: petrochemical industry, food and beverage, steel production, pharmaceuticals, plastics manufacturing and oil and gas.

Interface: ISO5211/DIN3337, VDI/VDE3845 (NAMUR).
Operating medias: air (even dry), non-corrosive fluids and gases.
Variations: high temperature, low temperature, fast acting, J-Switch (box) Certifications: SIL, ATEX, long life.

Specials: - Piston support rods with six bearings minimise internal wear and maximise performance life - Anodised aluminium construction for anti-corrosion and superior wear performance on internal surfaces - Multi-spring failsafe concept ensures actuator operation in the unlikely event of spring fracture (spring return models) - Unique unrestricted air flow through support rods gives fast operation speeds as standard – and also provides greater safety (centre chamber cannot be pressurised with end cap removed) - Compact failsafe size as per double-acting – minimises space requirements - All parts sealed and greased for life
