The 12 inch 600LB trunnion mounted ball valve has gearbox, RTJ flange, fire safe design per API 607. The 3 piece ball valve is designed per API 6D.
Design Feature & Benefit
1.Small flow resistance means less pressure drop
2.Simple valve structure and light weight
3.Diversified sealing material available, from metal material TCC, satellite, stainless steel to soft material PTFE, Teflon, Nylon, Peek and etc
4.Good performance of both metallic sealing and soft sealing
5.Convenient and swift operation of the valve
6.Easy to maintain due to renewable seat ring
7.When fully opened or closed, the valve sealing face is isolated from medium corrosion.
8.Wide range of application in terms of size and pressure rating

What is difference between floating and trunnion ball valve?
The ball part of floating ball valve is movable. Under the pressure of medium, the ball has a certain displacement and presses on the sealing surface of outlet end to ensure its tight sealing. The floating structure is suitable for ball valve with small size and low & medium pressure rating.
The ball part of trunnion mounted ball valve is fixed. Under the medium pressure, the floating seat will move towards the ball to ensure the sealing. The trunnion mounted ball valve is often with larger size and higher pressure.
