Pneumatic Torque Wrench – Angle Version ZPK

An electric torque wrench is a combination of a planetary transmission with an intermediate transmission and a drive provided with a pneumatic motor. The torque wrench collaborates with the pressure control unit that is made up of a water trap, an oil lubricator for compressed air and a manometer.

• Adjustment, i.e. setting of the desired torque is carried out by adjustment of the corresponding air pressure that is indicated on the attached monometer.
• Each machine is individually calibrated to establish the strict relationship between the desired torques and corresponding air pressure values (up to 6 bars), which is summarized in the table of torques attached to each machine.
• When the preset value of torque is reached the machine is automatically switched off that guarantees reliability of connections and exact repeatability of torques.
• The accuracy for constancy of torques is 3%.
