Double port pressure regulator with floating seat

摘要

A double port regulator assembly includes a first fluid port and a second fluid port. A fixed valve seat assembly is disposed proximate the first fluid port and a floating valve seat assembly is disposed proximate the second fluid port. A first valve plug cooperates with the fixed valve seat assembly to open and close the first fluid port and a second valve lug cooperates with the floating valve seat assembly to open and close the second fluid port. The floating valve seat assembly includes a floating valve seat that is movable with respect to the fixed valve seat.
