Abstract
A choke valve is provided having a body, a seat, and a gate. The body has an internal chamber, an inlet flow passage, and an outlet flow passage. The seat has a seat orifice with an area, the seat positioned at an end of the outlet flow passage contiguous with the internal chamber. The gate has a gate shaft and a gate body affixed to one end of the gate shaft. The gate is linearly translatable within the body between a fully open position and a fully closed position, wherein in the fully closed position the gate body is engaged with the seat orifice. In the fully open position a choke minimum passage area is defined between the gate body and the seat orifice, and the choke minimum passage area is at least 30% of the seat orifice area.
