An apparatus and method for a diaphragm valve includes a valve body having a chamber in fluid communication with a first channel and a second channel. A diaphragm is disposed in the chamber, and a tapered seat member is at least partially disposed in the first channel. A sleeve is compressively disposed in the seat member between the seat member and the first channel to maintain a fluid tight seal between the seat member and the first channel. A valve member is movable to controllably urge the diaphragm into and out of engagement with the seat member to control flow of fluid between the first the first and second channel.
