Pneumatic Torque Wrench VS Hydraulic Torque Wrench for Valve Manufacturer

Pneumatic torque wrenches and hydraulic torque wrenches are commonly used by valve manufacturers for pre-tightening, but which one is more suitable?

The use of pneumatic torque wrenches in indoor workshops only requires compressed air as a power source, does not require an additional hydraulic system, and produces less noise during work. In addition, the pneumatic torque wrench has a fast response speed, can quickly complete the bolt tightening task, and has high production efficiency. From these two aspects, the use of pneumatic torque wrench for bolt pre-tightening in the workshop has advantages over hydraulic wrench. However, the use of pneumatic torque wrenches may be limited in some circumstances, such as the occasions where work needs to be performed at high altitudes or in narrow spaces. At this time, a hydraulic torque wrench is required to pre-tighten high-torque bolts.

Therefore, which type of torque wrench to choose should be determined according to the specific work requirements and environmental conditions of each site, and the bolt pre-tightening tool suitable for specific working conditions should be selected.
