High vacuum angle valve series XL provides excellent thermal conductivity results in a uniform temperature for the entire valve body and a marked decrease in the condensation of gases inside the valve. The valve does not contain heavy metals such as Ni (nickel) or Cr (chrome) and a low sputtering yield also helps to minimize heavy metal contamination of semiconductor wafers.
It was confirmed that XLD-25, XLD-40 XLD-50, XLD-63 and XLD-80 satisfied the product specification up to 2 million cycles, XLD-100 and XLD-160 did up to 1 million cycles. Test piece posture: lateral : The test was performed with FKM, the standard sealing material.
