8.4.1.3 Precautions for Use of Negative Pressure Ball
Besides the seal cover, the front end of the negative pressure ball also has two check valves, as
shown in the following figure. The embedded check valve is connected to the inlet port of the
negative pressure ball and is used only for gas suction. The external check valve is used only for
scavenging. If the pre-seal cover is removed or loose, the sealing performance of the negative
pressure ball is degraded. In this case, fasten the seal cover.
If the negative pressure ball is connected to a tested component, the negative pressure ball is used
only for gas inlet. However, if the negative pressure ball is squeezed, the air is exhausted.
