DESIGN AND TECHNICAL FEATURES 1.Pistons design Dual piston rack and pinion for compact construction, symmetric mounting position, high-cycle life and fast operation. Reverse rotation can be accomplished in the field by simply inverting the pistons. Both pistons are anodized for a better corrosion and wearing resistance. 2.Two independent external travel stop adjustments As standard, travel stops allowing adjustment for 5 up to +15 on the close position, and for + 5 up to -15 on the open position. This allows accurate valve alignment, stroke limitation and provides on actuator a large travel adjustment. 3.Universal and anti-blowout drive shaft The double square option allows an easy parallel or diagonal fit and vice versa. See page 7. 4.Drive shaft top adaptor The aluminum top adaptor for ancillary driving/attachment gives a more precise and stable coupling with ancillary stem suitable for higher temperature application. 5.One compact and modern design With identical body and end caps for double acting and spring return model to reduce inventory, allows field conversion, by adding or removing modular spring cartridge. For this conversion, Lupatech Valmicro must be consulted to evaluate the resultant torques. 6.Position indication The combination of the new top adaptor and the new position indicators allows to achieve easily the correct actuator/valve position indication by just rotating of 90 the top adaptor and the indicator. This operation can be easily done also on the field by avoiding ing the actuator disassembling. 7.Multiple bearing and guide Bearing on piston and racks for precise operation, low friction, high cycle life and piston guides preventing shaft blowout. 8.Modular preloaded springs Cartridge design in high grade Coated steel for simple range versatility, greater safety and corrosion on resistance. 9.Electroless nickel-plated drive-shaft Blow-out proof, bearing guided for improved safety and maximum cycle life. 10.Fully machine teeth On piston racks and pinion shaft for accurate positioning, low backlash and maximum engagement resulting in overall efficient operation. 11.Selected and high quality bearing and seals Provide a wide operating temperature range, low friction and high cycle life. 95 90 75 Stroke 15 0-5
DESIGN AND TECHNICAL FEATURES 12.Fasteners Stainless steel fasteners for long term corrosion resistance. 13.Full compliance To specifications ISO 5211, DIN 3337, and VDI/VDE 3845 providing the product interchangeability and the easiest valve automation and accessories installation. 14.High quality level production The 4th Generation Line pneumatic actuators, Upgrade Series, have been designed and tested to obtain the highest cycling life and the most reliable performance with very reduced maintenance and service. 15.Technology and material The 4th Generation Line pneumatic actuators, Upgrade Series, are manufactured with the highest material quality, the most accurate material selections and the latest production technologies. ACTUATOR OPERATING CONDITIONS 1. Operating media Dry or lubricated air, inert/non-corrosive gases provided that they are compatible with the internal actuator parts. 2. Supply pressure For Double Acting and Spring Return actuators the maximum supply pressure is up to 8 bar (116 PSI), the minimum supply pressure is 3 bar (43,5 PSI). 3. Working Temperature Standard actuator construction suitable from - 40 C (-40 F) to + C (+176 F). 4. Lubrication Actuators are factory lubricated for life under normal operating conditions. The standard lubricant is suitable for use from -40 C (-40 F) to + C (+176 F). 5. Installation Actuator suitable both for indoor and outdoor installation. 6. Protection and Corrosion resistance Extruded aluminum body with Alodur special hard anodization applied internally and externally for a complete corrosion protection, a lower friction coefficient and an increased surface hardness for the longest wearing resistance. Alodur hard anodizing is a process of electrolytic conversion, that produce a protector oxide layer. This anodized layer has nearly 50 μm, and the parts gets high corrosion resistance in salt spray and immersion test, and also stress corrosion cracking. The oxide layer is integrated with the substratum and will not deteriorate by thermal shock, in temperatures near the aluminum fusion point. The aluminum oxide is one of the most hard material known, with hardness from 45 up to 65 Rockwell C. The aluminum oxide is relatively stable and chemical inert in a ph range between 4,5 and 8,5, but can be dissolved by strong acids and alkali, however usually resists to concentrated nitric acid with ph 1 and ammonium hydroxide with ph 13.
ACTUATOR FUNCTION AND ROTATION On the standard actuator, rotation is clockwise to close. A counter-clockwise rotation is achieved when port 2 is pressurized. Double Acting operation function (standard rotation) TOP View: Air supplied to port 2 forces the pistons towards the actuator end caps. With the exhaust air exiting from port 4, a counterclockwise rotation is achieved. Air supplied to port 4 forces the pistons inward. With exhaust air exiting from port 2, a clockwise rotation is achieved. "2" "4" "2" "4" Single Acting operation function (standard rotation) TOP View: Air supplied to port 2 forces the pistons toward the actuator end caps, compressing the springs. With the exhaust air exiting from port 4, a counter clockwise rotation is achieved. The loss of air pressure (pneumatic or eletric failure) at port 2 allows the springs to force the pistons inward, releasing the air through the port 2 and achieving a "2" "4" "2" "4" clockwise rotation. POSITION INDICATOR AND TOP ADAPTOR Options available for AT045U to AT101U Standard position indicator with stainless steel insert to assist the driving/attachment for a more precise and stable coupling with ancillary stem. A graduated ring is fitted under the position indicator in order to have an accurate position indication. Optional indicators for direct mounting of sensors (P+F, IFM, etc.) and mechanical limit-switches. Options available for AT201U to AT1U Standard position indicator with aluminum top adaptor for ancillary driving/attachment for a more precise and stable coupling with ancillary stem. A graduated ring is fitted, under the position indicator in order to have an accurate position indication. Optional indicators for direct mounting of sensors (P+F, IFM, etc.) and mechanical limit-switches.
IN LINE AND ACROSS LINE ACTUATOR INSTALLATION VERSATILITY The patented design of the top adaptor in combination with the position indicator allows to easily achieve the right actuator/valve position since both can be easily fitted in any 45 position. Therefore during the valve automation it is not necessary to reassemble the drive shaft in order to achieve the correct position indication. The top adaptor is suitable and available for any drive shaft connections like single square (diagonal and parallel), double square, head flat or key head. Actuator in close position and IN LINE installation Actuator in close position and ACROSS LINE installation (top adaptor and position indicator 90 rotated)

The value thus obtained is then compared with figures in the minimum air pressure column in the actuator torque tables. After having found the same or nearest value (in excess), the suitable actuator model can be read from the column to the left. Torque output spring return Air Torque Spring Torque 0 90 Spring Action Air Action The spring return actuator has four different torque values: the air torques at 0 and 90 when it is pressurized, and the spring torques at 90 and 0 when the pressure is discharged. For a correct sizing, the torque of the actuator in both strokes have to be higher than the valve torque curves. Also for the spring return actuator sizing, the valve torques have to be multiplied by a safety factor (usually at least 25% - % depending on the valve and service). The 4th Generation Line Upgrade Series are designed to give a balanced torque when the number of springs per side is equal to the air pressure supply in bar (for example 4 bar, 4 springs per side).

If the actuator is over dimensioned, the valve stem might be damaged, or else, if the actuator is under dimensioned it will not be able to produce enough torque to allow the correct valve operation. It is usually said that the required torque for the valve operation comes from the friction between the metal parts of the valve and the sealing (seats and gaskets). In addition, the torque depends on different factors, such as valve application (working conditions), working temperature, operational frequency, line and differential pressure, fluid characteristics (lubricated, dry or dirty).
