Full bore ball valves are usually used for throttling applications in various systems with high flow coefficients ...
What is true union valve?
True union (Trunnion) True union ball valves have a pin in place which secures the ball in place and stops its movements. Two shafts at the opposite ends of the ball in Trunnion enable the supporting of a segmented ball by the valve and enable the system to cause less friction between different parts of the true union valve.
What does a V port valve mean?
The V in the v-port ball valve represents either the shape of the seat or the shape of the ball. V ball valve enables you to control the opening and the closing better. The flow characteristic in this type is close to linear. The high velocities of the fluids used with such ball valves forced the designers to come up with generally more robust construction for them since these types of fluids quickly damage a standard valve.
