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
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 Torque from 15 Nm to 4000 Nm Mounting flange according to EN ISO 5211 F03 - F04 - F05 - F07 - F10 - F12 - F14 - F16 -F25 In compliance with EN 15714-3 Rotation angle: 92° (-1°, +91°) Torque: the return torque depends on spring action only notwithstanding the air supply. The spring is provided in four different sizes (see table) The actuator automatic closing takes place in clockwise direction by means of its springs In the code of standard version GS actuators, it is indicated the size of the springs (6=5,6 bar) followed by the breakaway torque in Nm at 5,6 bar air supply. ATEX version in conformity with directive 2014/34/EU
WORKING CONDITION 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 lubricated air, either non detergent oil, NBR compatible oil, must be used.
