GD720-GD3840
GD720-GD3840 (actuators can also be produced in carbon steel, with painting colours and details on request)

1.Energized and self-lubricated strips
Less friction between piston and cylinder
It prevents the bonding of the seal to the cylinder even after long periods of inactivity

2.Slots, bushes and pins made by steel with hardness higher than 50 HRC
Higher resistance to the forces inside the actuator

3.Rolling friction between piston and slot
Less friction

4.Scotch yoke with rolling friction (transforming rotary motion into linear motion using piston and shaft without teeths/gears)
Reduced friction between piston and shaft with consequently less wear on the relevant parts
Empowered Breakaway Torque (BTO & BTC)
Smaller volume/size than rack and pinion actuators (with the same torque) therefore less space required for installation
Less weight than the rack and pinion (-30% kg / Nm), with consequent savings on the construction sizing of the plant/equipment
Lower air consumption compared to the rack and pinion actuators (-40% air cm3/Nm for Double Acting and -20% air cm3/Nm for Spring Return) therefore less load on the compressor or the possibility of using a smaller compressor's size.

5.Rolled cylinder

Less wear of the energized ties thanks to the low roughness of the surface (0.15 micron Ra)

From sizes bigger than GD15, NAMUR interface for solenoid valve is already integrated.
No need for extra plate.

100% in- house manufacturing process technology
Maximum control and accuracy in all the stages of the manufacturing process

ATEX Certificate
Installation is allowed in a potential explosive environment

Up to SIL 3 Certified
Guarantee of the high level of functional safety.

TECHNICAL FEATURES

Mounting flange according to EN ISO 5211
F10 - F12 - F14 - F16
In compliance with EN 15714-3
Rotation angle: 92° (-1°, +91°)
Torque: directly proportional to the air supply (see table - general catalogue pneumatic actuator GD)
In the code of standard version GD actuators, it is indicated the breakaway torque in Nm at 5,6 bar air supply.

GD PNEUMATIC ACTUATOR OPERATING DIAGRAM

Drawings on the left = valve in open position
Drawings on the right = valve in closed position


Typical air connection diagram
Port 2 connects to the side chambers of the cylinder: by supplying pressurized air to port 2, the drive shaft of the Standard Double Acting actuator rotates anticlockwise to open. Port 4 is instead connected to the middle chamber: when it is pressurized, the shaft rotates clockwise to close. The remote control to operate the actuator must be performed by connecting the solenoid valve firectly to the standard interface of the VDE/VDI 3845 NAMUR actuator, or by means of pipes screwed onto the ports marked with numbers 2 and 4 (connected to a separate electrical cabinet).
In accordance with the international standard ISO 5599-2, the position, location, orientation and shape of the actuator air port connections must be clearly identified and marketed using numbers 2 and 4.
