Clean, Press and Wait for Strong Adhesion
01Release the air and remove the old valve
Lift up the vehicle, release the tire pressure, remove the tire, and remove the old valve; Clean the rust and residue of the wheel rim installation holes and old sealing rings, and check for any deformation or burrs in the hole positions.
02Assemble a brand new tire valve and seal it
Lock evenly with standard torque to prevent deviation and slow air leakage; Adjust the valve angle to avoid friction with the tire wall, and install a brand new high-temperature resistant valve core.
03Testing+Dynamic Balance Loading
Inflate to the standard tire pressure of the vehicle and check for any air leaks; Perform tire dynamic balancing; Recheck the tire pressure during the loading road test to confirm that there is no leakage or shaking, and then complete the replacement.
Tip: Control the torque and avoid violent twisting. Excessive torque can cause fracturing of the rubber ring and deformation of the wheel rim hole; Insufficient torque leads to turbulence, looseness, and air leakage in the later stage.
Controlled Details from Weight Accuracy to Finished Packing
01Incoming Material Inspection
100% sampling inspection of all raw materials; The spectrometer detects the composition of brass material to eliminate the problems of cracking and corrosion caused by impurities in copper.
02Process Inspection
Micrometer measuring rod length, base diameter, thread; Full inspection of thread gauge to ensure smooth assembly without slipping threads.. Remove semi-finished products that are prone to rust.
03Airtightness Test
High pressure airtight water immersion test: Simulate the working pressure of a heavy truck at 14Bar to maintain pressure, and observe the entire process without any bubbles or leaks; Torque and voltage withstand test.
04Final Inspection
Full inspection of appearance scratches, coating peeling, and laser logo clarity; Control the weight tolerance of the entire machine to ensure stable dynamic balance.
