Trunnion mounted ball vaIve

Views:

Trunnion mounted ball valve is a new generation of high-performance ball valve, suitable for long distance pipelines and general industrial pipelines. Designation takes full consideration to its strength, safety, resistant to harsh environments, so it can apply to a variety of corrosive and non-corrosive media.It is used to cut off or connect the media in various pipelines of Class 150~Class 2500.

The valves are made of different materials,which are suitable for various media such as water,oil,liquefied gas,natural gas,etc. The double piston effect design (available on request), maintains the sealing capacity of the valve even in the case of failure of the up stream seats, Bodg cavity over pressure in this case can be released through a relief valve to atmosphere. The tightness is assured by the piston effect acting on the seat, pressing it against the ball, once the valve is pressurized.


Dimension rangeNPS 2”~48"
