The Mars Ball Valve has a blow out proof stem and an antistatic device between the stem and body and stem and ball. The high cycle life stem design is accomplished by a double sealing system. The 45° Pyramidal Segment Ring in conjunction with a seal that fits on top of the Pyramidal segment provides the primary seal. Most of the media in the pipeline is contained by this seal. As a precautionary measure a V ring chevron packing provides the secondary sealing. On top of the stem is a set of Belleville washers that automatically adjusts compression to the seal to compensate for wear, pressure or temperature fluctuations.
