Abstract

A valve for conveying fluid has a closed position and an open position and comprises a body, a valve seat disposed in the body, a holder disposed in the body, and a valve seat disc. The valve seat comprises one or more inner surfaces and an outer surface, and the one or more inner surfaces define an inner void. The valve seat disc is connected to and movable with the holder between a first position in which the valve seat disc sealingly engages the outer surface of the valve seat and a second position in which the valve seat disc is disengaged from the outer surface of the valve seat. The valve is in the closed position when the valve seat disc is in the first position and the valve is in the open position when the valve seat disc is in the second position.
