The dimension parameter of the CF-ISO high-velocity relief valve：

Remarks：flange executive standards：GB******9，DN**-DN**0, nominal pressure is 0.6Mpa; DN**0、DN**0， nominal pressure is 1.6Mpa（is equal to ISO********4、ISO********5）。
三、The main performance parameter of CF-ISO high-velocity relief valve：
  　　Remarks：1、The high-velocity relief valves with different specifications have the same diameter and performance parameter;
2、The opening pressure of the vacuum valves are *3.5kPa; the opening pressure of the pressure valves on the oil tank is *4kPa, on the chemical tank is ****0kPa. the opening pressure of the pressure may be different, but the differences of opening pressure and flow range is inapparent if the pressure valves have the same diameter.
