Product Features
DOUBLE ACT PNEUMATIC ACTUATORS

PRODUCT DESCRIPTION
Innovative new design NST-DA Series Nordsteam pneumatic actuators are rack & pinion designed,which are produced as double acting types.The products oprerate at 0° and 90°angles,but adjustable with the tolerance of ± 5° by the two adjustment screws on the body as standard in the direction of both opening and closing.On the other hand,as optional, there are also our models which can be fully adjustable among 0° and 90° angles.With their improved and ideal designs,NST-DA Series Pneumatic Actuators have higher torque output values without increasing the diameter of piston and have a longer service life.

The Operating Principles and Torque Values of Double Act Actuator
Double Act Actuators are turned on or off by air and controlled with 5/2 or 5/3 Namur selenoid valves, their operating principles are below;
Counter Clockwise Rotation (CCW) : the air supplied to Port B pushes the two pistons outwards by turning the shaft in the direction of counter clockwise, meanwhile the air between two sides of the actuator is discharged from port A which is open.
Clockwise Rotation (CW) : The air supplied to Port A pushes the two pistons inwards by turning the shaft in the direction of clockwise, meanwhile the air between two pistons is discharged from port B which is open.
