Pneumatic
VASI supplies Norbar non-impact, high precision, pneumatic torque tools for bolting, valves, and other applications.
Torque control is achieved by adjusting the air pressure via an air pressure regulator. An air pressure versus torque graph and a calibration certificate is supplied with each individual tool and allows specific torque values to be set. To achieve this, you use a Lubro Control Unit.
Most Pneumatic torque tools can also be fitted with an electronic torque transducer.
