Torque is controlled by adjusting hydraulic pressure using the pump and referencing the wrench torque chart.
Torque is controlled by adjusting hydraulic pressure using the pump and referencing the wrench torque chart.
Hydraulic torque wrench systems produce torque output based on hydraulic pressure. The operator sets the pump pressure to a specific PSI value and uses the manufacturer torque chart to match that pressure to the required torque output. This allows consistent bolt tightening across multiple fasteners and helps prevent over-torque or under-torque conditions. Accurate pressure gauges are essential for safe bolting performance.
