摘要： A pressure regulator (210) including a body (212) having and a valve seat (320) supported in the body for movement relative to the body for allowing the position of the valve seat to float relative to the body, the valve seat being resiliently biased downward in a first direction and movable upward in a second direction as a function of inlet pressure of fluid flowing through the flow passage. The floating seat (370) thereby allows for the outlet pressure at high inlet pressure to be similar to the outlet pressure at low inlet pressure and high flow to reduce the pressure control envelope, thereby reducing size, weight, and cost of the pressure regulator and allowing for a larger poppet to be utilized.
