Spring Return Pneumatic Actuator “SR” TypeSR

A1

...... .... ...

........

Torque from 15 Nm to 1920 Nm.Mounting flange according to DIN/ISO 5211 DIN 3337F03 - F04 - F05 - F07 - F10 - F12 - F14 - F16.NAMUR connection for accessories.Rotation angle 90ÁTorque: the return torque depends on spring action only notwith-standing the air supply. The spring is provided in four different sizes(see table).The code numbers after the letters SR, always correspond to thebreakaway torque in Nm by 5,6 bar air supply.The actuator automatic closing takes place in clockwise direction bymeans of its springs.

WORKING CONDITIONTemperature: from 0ÁC to +80ÁC; from -20ÁC to +80ÁC with dry aironly. (+150ÁC in special execution)Air supply: 5,6 bar; maximum 8,4 bar.Operating media: compressed filtered air, not necessarily lubrica-ted.In case of lubricated air, either non detergent oil or NBR compatibleoil, must be used.
