METHOD FOR FLUID PRESSURE CONTROL IN A CLOSED SYSTEM |
| 摘要 |
A method for controlling a system pressure within a closed system includes sending a signal to a pressure control valve corresponding to a pressure set point and actuating the pressure control valve to vary a pilot pressure of a control fluid contained within a pressure control line that is fluidly connected to a pressure regulator. A diaphragm of the pressure regulator is disposed between the pressure control line and a system line and acts on a fluid with the system line to modify the system pressure. |

1. A method for controlling a system pressure within a closed system includes:
sending a signal to a pressure control valve corresponding to a pressure set point; and actuating the pressure control valve to vary a pilot pressure of a control fluid contained within a pressure control line that is fluidly connected to a pressure regulator, wherein a diaphragm of the pressure regulator disposed between the pressure control line and a system line acts on a fluid within the system line to modify the system pressure. |
