Norbro Series 40R actuator

The Norbro actuator is recognised as the leading name in the quarter turn pneumatic actuator market. Designed for high performance and reliability using the unique guide rod design, the Flowserve Norbro can be used in a wide range of applications.

The actuator is also designed for safety and ease of maintenance using features such as anti-blow out pinion and long end cap screws to release spring energy.


  • Unique guide rod design for long life
  • Double acting and spring return in same body size
  • Anti-blow out pinion
  • Namur (VDI/VDE) solenoid and top mounting
  • ISO mounting platform
  • Large size range

With eleven sizes in the range the torque outut can be closely matched to the required valve torque to provide a competive actuated package

Norbro series P61 Two stage actuator

Designed for the control of batch/filling operations, the P61 provides rapid, repeatable and highly accurate control in both level of weigh measuring processes

The valve uses the basic spring return Norbo with additional pistons allowing the actuator to be adjusted to a semi closed position for trickle flow before finally closing the filling valve. This stage is manually adjustable and therfore highly repeatable

Available in 7 sizes from the Norbro range with DIN ISO 3337 mounting platform.


  • High repeatability for batch filling operations
  • DIN-ISO 5211 mounting pattern
  • Available in 7 sizes
  • Based upon the conventional Norbro 40R

Automax Super Nova actuator

Automax Supernova series Rack and Pinion actuators are designed for butterfly, plug, or ball valves, and offer one compact design for double acting and spring return. Precision die-cast pistons with large cylinder bearings increases efficiencey and cycle life. The actuators incorporate a precision-extruded hard anodized aluminium body and a one piece nitride coated or nickel-plated pinion gear, factory lubricated for a long trouble-free life.

The actuators are designed for 100 degree travel with clockwise and counterclockwise travel adjustment for open and closed positions up to Size 200. Available in torque ranges from 8 Nm to 5,005 Nm, for optimum actuator sizing.


  • Field reversible action simply by rotating pistons 180 deg
  • One compact design for double acting and spring return is easily field convertible by installing or removing springs
  • Broad size range offers optimum actuator sizing for each valve requirement
  • Corrosion resistant, hard anodised aluminium housings with stainless steel fasteners
  • Integral travel stops

Automax R Series Heavy Duty actuator

The R2, R3 and R4, Series Scotch Yoke heavy-duty actuators provide torques from 1,000 to 17,000 in-lbs. The combination of Scotch Yoke actuators, Rack and Pinion actuators, plus Automax's extensive range of automation products offers the opportunity to standardize on one source for your complete quarter-turn automation needs. The R Series actuators can also be configured with high pressure hydraulic cylinders.

The R5 Series heavy duty scotch yoke actuator provides torque output as high as 500,000 in lbs. Piston rods are guided and supported by self lubricating bronze bearings. The slot in the R5 scotch yoke mechanism is precision machined. The yoke pin is is induction hardened and chrome plated. It is supported at the top and bottom by a guide in the slot in the housing and the yoke pin rollers are hardened steel

Valtek Linear actuator

The VL spring cylinder linear actuator is a powerful, high-performance pneumatic actuator that provides positive throttling or on-off operation for automatic control valves. Most cylinder sizes are designed for supply pressures up to 150 psi (10.3 Bar). Using a spring to provide failsafe operation, this actuator is completely field reversible for air-to-open or air-to-close operation without additional parts. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response.


  • Decades of Reliable Service
  • High Thrust Capabilities
  • Long Stroke Lengths
  • Compact and Lightweight
  • Simple Maintenance
