A valve plug includes a cylinder, a first plug seat, a second plug seat, and a convoluted portion. The cylinder has a first and second end. The first plug seat is disposed at the first end. The second plug seat is disposed proximal to the second end. The convoluted portion is disposed between the first seat and the second seat. The convoluted portion provides flexibility for the cylinder to flex between the first plug seat and the second plug seat.

Balanced double seated globe valve with flexible plub

The present invention relates to an apparatus and method of deploying a desuperheater with a Seat-Ring designed to provide coolant injection at high temperature differential. The present invention's robust design provides for a high level of flexibility that allows operating at high temperature differentials between the coolant and the superheated fluid. The desuperheater Seat-Ring is made as a split hollow ring with a perpendicular slit traversing the ring's circumference. The opened slit design provides a high level of flexibility, which allows the seat ring to sustain severe temperature extremes by reducing thermal stress. The coolant is supplied to the seat ring through a specially designed coolant nipple liner connected to the seat-ring.
