Trunnion ball valve design
- Trunnion Mounted Structure used to seal or block the flow of whatever is in the pipe.
- Valve weight, size, and material strictly conform to the API standard.
- A mounted ball valve with a bleeder is required to make sure that pressure surges in pipes are controlled or avoided.
- Ideal for bi-directional sealing. It can stop or block the movement of the upstream and downstream flow.

What is a Trunnion Ball Valve?
High-pressure operations are what is trunnion ball valve is ideal for. The design anchors the ball valve trunnion meaning a seal for both upwards and downward streams are achieved.
XHVAL industrial valve co has different types and materials for every trunnion ball valve need, in whatever application is required. Spanning over three decades of expertise, XHVAL trunnion ball valve manufacturers produce customized ball valves made from the highest quality materials and that adhere to the top API standard.
Advantages of the Trunnion-mounted Ball Valve
Lower operating torque
The operating torque of the trunnion-mounted ball valves is reduced due to additional support provided by the trunnion, giving reinforcement to the bottom of the ball and the top.
Ease of operation
A quarter-turn is easier to operate as opposed to valves that a require a full turn. It is preferred by industries that require quick maneuverability and shut-off.
Minimized seat wear
The isolated nature of the trunnion-mounted ball prevents the wear of seats resulting in its durability and longer service life.
High and low-pressure control
It is ideal for high and low-pressure control because of the sealing of the ball valve by a separate spring mechanism.

Trunnion Ball Valve vs Floating
The main difference between the ball valve trunnion vs floating ball valve lies in their mechanism. The floating ball valve is only connected to a top shaft or the valve stem, while the trunnion-mounted valve’s ball is connected to a bottom shaft or the trunnion.
