XLF, O-ring Seal, Normally Closed

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. XLF is a normally closed, single acting high vacuum angle valve with an O-ring shaft seal.  The XL*-2 family shares common features with all series members.  Bodies are made of aluminum for light weight and excellent thermal conductivity, resulting in a uniform temperature for the entire valve body.  The body offers excellent resistance to fluorine corrosion.  A low sputtering yield and the absence of heavy metals avoid wafer contamination.
