For best results we recommend selecting an actuatormodel with a minimum output torque that is greater than the highest operating torque of the valve to beactuated, plus 10%.Example for Double Acting (DA) Actuator Sizing:Published Valve Torque:300 in-lbs (plus 10% safety factor 330 in-lbf)Air Supply: 80 psigaero2 Model: A2D-35The A2D-35 has the output torque value of 356 in-lbf @ 80 psig.Example for Spring Return (SR) Actuator Sizing:Published Valve Torque:300 in-lbs (plus 10% safety factor 330 in-lbf)Air Supply: 80 psigaero2 Model:A2S-110 (10 Springs - Standard)The A2S-110 has the following output torque values @ 80 psig:Air End: 543 in-lbfSpring End: 413 in-lbfSizing Safety FactorsMedia and other conditions can effect the operating torque of a valve.Following is a list of common Safety Factors.MEDIASAFETY FACTORBasic Value 1.0Liquid, clean (particle free)1.0Gas, clean and wet (saturated steam)1.0Gas, dry (superheated steam)1.3Gas, dirty (natural gas)1.5Oxygen, Chlorine 1.5Liquid, dirty (slurry), raw water1.8Paste/Paint 1.8An aero2 Actuator Sizing Guide configurator is available on our website: www.SVF.net/ aero2 actuator sizing.phpSpecifications subject to change.
