Abstract
Dome-loaded pressure regulators are disclosed. An example pressure regulator includes body having a pressure inlet and a pressure outlet. A piston is disposed in the body and fluidly coupled to the pressure inlet, the pressure outlet, and the pressure control inlet. The piston is configured to contact a valve seat and to control the flow of fluid from the pressure inlet to the pressure outlet in response to a pressure applied to a surface of the piston via the pressure control inlet.
Claims20
A pressure regulator, comprising:
- a body having a pressure inlet and a pressure outlet;
- and
- a piston disposed in the body and fluidly coupled to the pressure inlet, the pressure outlet, and the pressure control inlet, wherein the piston is configured to contact a valve seat and to control the flow of fluid from the pressure inlet to the pressure outlet in response to a pressure applied to a surface of the piston via the pressure control inlet.
A pressure regulator, comprising:
- a dome-loaded pressure regulating valve fluidly coupled to a pressure inlet, a pressure outlet, and a control pressure, wherein the pressure regulating valve comprises a piston 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.
A pressure regulator, comprising:
- a body having a pressure inlet and first and second pressure outlets;
- and
- first and second pressure regulating valves disposed in the body and fluidly coupled to the pressure inlet and the respective first and second pressure outlets, wherein each of the first and second pressure regulating valves includes a piston having a first portion to receive a control pressure and a second portion fixed to the first portion and configured to sealingly engage a valve seat.
