ABSTRACT:
A flow-through pressure regulator includes a divider, a closure member and a housing. The divider separates a first chamber from a second chamber, and includes a passage that provides fluid communication between the first and second chambers. The closure member moves relative to the divider between first and second configurations. The first configuration substantially prevents fluid communication through the passage, and the second configuration permits fluid communication through the passage. The housing includes a first homogeneous housing portion and a second housing portion. The first homogeneous housing portion includes an inlet, defines the first chamber, and forms a pocket that receives a majority of the closure member. The second housing portion includes an outlet and defines the second chamber.
