Howdy! Thank you for posting your query about the Fresno F031-32052 pressure relief valve. To determine the pounds (lbs) you are setting on the Fresno F031-32052, you would typically use a torque wrench. A torque wrench allows you to set a specific amount of force or torque in pounds.

To set the pounds, you would first need to know the specific torque specifications for the application you are working on. These specifications can usually be found in the equipment or machinery's manual, or they may be provided by the manufacturer.

Once you have the torque specifications, you can adjust the torque setting on the torque wrench. Twist the handle or use the adjustment knob on the wrench to set it to the desired pounds.

After properly setting the torque on the wrench, you can then use it to tighten or loosen bolts or fasteners with precision, ensuring they are tightened to the correct torque specification. Thank you for trusting PlumbersStock. Have a great day!
