TORQUE TABLE Nm (Double Acting)
Selection of actuator base on air supply 6bar.
First determine the valve torque with 30% allowance for example ball valve size 2'' 50Nm, add 30% become 65Nm.
Look at the 6bar column for actuator torque value greater than 65Nm
RD80 at 6bar 76Nm

TORQUE TABLE Nm (Spring Return)
Selection of actuator base on air supply 6bar, and 10 units of spring.
First determine the valve torque with 30% allowance for example ball valve size 2'' 50Nm, add 30% become 65Nm.
Look at the 6bar column (highlighted), torque value must be greater than 65Nm for both ''Air to open'' and ''Spring to close'' and 0° and 90°
RS125 air to open from 0°~90° torgue 221Nm~148Nm. Spring to close from 90°~0° torque 163Nm~91Nm.
Alternative:-
RS115 with 12 units of spring
Air to open from 0°~90° torgue 170Nm~116Nm. Spring to close from 90°~0° torque 121Nm~74Nm.
