MMEngineers - IV1T & IV3T Series

The trunion design high performance ball valves use the upper and lower supports to retain the ball under pressure. It allows the valve to be installed in either direction. This valve can be used in applications with reversing flow.

Another feature of trunion design is that it allows the ball valve to act as a true union. This allows down stream piping to be disconnected under full upstream pressure (provided the downstream piping is drained of liquid and that the valve is indeed closed and secured to upstream piping). The trunion on a two way ball valve supports the ball in much the same way as the stem does on top.
