Permanent Quality Control

Vincent counts on the most developed equipments to carry out all control

and testing operations: hydraulic and pneumatic air tightness testing , dimensional control ,material 

control,operating and resistance testing.  



      Material Control 
Chemical analysis by spectrometer. 








② Metal Hardness Test
  Mechanical property test especially after heat treatment. 









 XYZ Test 
XYZ test of tolerance and size exactly according to the drawing.
 Noise Test

Environment protected by reducing noise of the valve.









⑤ Metal Thickness Test 
Thickness test to ensure the shell resistence.









⑥ Coating Thickness Test
Anti-errosion property made assrurance by thickness test after Epoxy painting and coating. 









⑦ Torque Test
Torque control to adapt to suitable actuator enlength using life.








⑧ Hydraulic Tests
Bi-direction test for every single piece of valve to make sure the sealing performance .









⑨ Rate of spheroidization
Test the rate of spheroidization every batch, less than level four.









 Rubber & PTFE & TPEE etc Hardness Test
Hardness test for sealing part to zero leakage.
