Product Description

The Mars Ball Valve has a blow out proof stem and an antistatic device between the stem and body and stem and ball. Fully encapsulated body seals allows welding in line without disassembly.

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.
