Abstract
A valve for use in a cabin pressure control system includes a valve body and a poppet. The valve body includes an inlet, an outlet, and a fluid flow passage therebetween. The poppet is disposed in the valve body. The poppet is moveable between at least a closed position, in which the poppet at least substantially restricts fluid from flowing through the fluid flow passage, and an open position, in which fluid is allowed to flow through the fluid flow passage. The valve body, the poppet, or both, have a fluorocarbon coating.
