Abstract
Dome-loaded pressure regulators are disclosed. An example pressure regulator includes a dome-loaded pressure regulating valve fluidly coupled to a pressure inlet, a pressure outlet, and a control pressure. The pressure regulating valve includes a piston, having a transverse bore defining a fluid path through the piston to fluidly couple the pressure inlet to the pressure outlet configured to engage a valve seat and to respond to the control pressure to control the flow of fluid between the pressure inlet and the pressure outlet via the valve seat.
