Valves filled with fuel oil in laboratory setting have exhibited a 75 psi increase in pressure with a

temperature rise of only 1°F.So when the trunnion mounted ball valve is installed

at an open field when the heat from the sun is very hot at the day time the fuel oil will expand inside the body cavity caused by the heat of the sun & the

fuel oil pressure inside the cavity will increase !

In case the fluid pressure inside the body cavity increases the cavity fluid pressure will push the floating seat ring forward the excessive fluid pressure will be relieved from the body cavity to the downstream of the ball
