GDV3840
Open and closed position
Before

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

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

TECHNICAL FEATURES
Torque from 60 Nm to 3840 Nm
Mounting flange according to EN ISO 5211
F05 - F07 - F10 - F12 - F14 - F16
In accordance with EN 15714-3
Rotation angle: 92° (-1°, +91°)
Torque: directly proportional to the air supply (see table)
The code numbers after the GD letters, always correspond to the breakaway torque in Nm by 5,6 bar air supply
ATEX version in conformity with directive 2014/34/EU

WORKING CONDITIONS
Temperature: from -20°C to +80°C. (Special versions: high temperature: -20°C +150°C; low temperature: -50°C +60°)
Air supply: 5,6 bar; maximum 8,4 bar
Actuating media: filtered dry compressed air, not necessarily lubricated
In case of lubrication use non-detergent oil compatible with the internal materials of the actuator version you are using

Once required the quarter turn pneumatic actuator can be equipped with a manual handwheel.
The device can be integrated either in Double Acting and Spring Return versions.
For the proper functioning of the system and for the mechanical integrity of the device is essential to ensure that the pneumatic actuator is disconnected from the power lines of compressed air before performing any operation using the manual handwheel.
The manual handwheel acts on the transmission of the primary mechanical transmission of the pneumatic actuator and with torques applied to the handwheel according to EN 12570 it releases output torque of equal value of the nominal torque of the actuator.

Actuator operating diagram with integrated manual override

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.
