This special construction for Trunnion Mounted valves allows easy on-site maintenance and
disassembly with quick access to ball and seats for inspection and repair. This is possible by
removing the bonnet of the Top-entry valve, allowing free access to the body cavity without
dismantling the valve from the line.

Top Entry valves are suitable and preferred for a wide range of high-risk industry applications
from severe abrasive and slurry to high temperature and cryogenic services, from LNG plants
to topside installations, especially in Off-shore plants where the on-site maintenance is of
utmost importance.
