Gas Line Control System and Modular Variable Pressure Controller

Patent number: US 9,400,060

Abstract: A pneumatically controlled assembly, system, method and device for the regulation of pressure of a gas as it flows in a pressurized line and including at least one loading valve which is set to respond to variations in pressure in conjunction with a pneumatically actuated process control valve so as to effectively regulate and maintain pressure of the gas in the pressurized line.

Type: Grant

Date of Patent: July 26, 2016

Assignee: VRG Controls, LLC

Inventors: James Michael Garvey, Vladimir Rimboym

Gas Line Control System and Modular Variable Pressure Controller

Patent number: US 10,234,047

Abstract: A pneumatically controlled assembly, system, method and device for the regulation of pressure of a gas as it flows in a pressurized line and including at least one loading valve which is set to respond to variations in pressure in conjunction with a pneumatically actuated process control valve so as to effectively regulate and maintain pressure of the gas in the pressurized line.

Type: Grant

Date of Patent: March 19, 2019

Assignee: VRG Controls, LLC

Inventors: James Michael Garvey, Vladimir Rimboym

Anti-Surge Recycle Valve

Patent number: US 11,624,456 B2

Abstract: An anti-surge recycle valve system for a natural gas line using a pipeline rotary control valve for controlling gas flow through the gas line and a valve controller having a surge-programmable feature including a threshold setpoint deviation limit, which is used to control first and second control valve loops. The first solenoid valve loop drives a rotary high-pressure piston actuator when the linear position sensor determines a setpoint deviation in gas flow below the threshold deviation, and the second solenoid valve loop drives the rotary high-pressure piston actuator when the linear position sensor determines a setpoint deviation in gas flow above the threshold deviation. The system provides ultra-rapid stroking speed in tandem with highly accurate and stable positioning.

Gas Control System and Method with Bracketed Deadband

Patent number: US 20230392756A1

A control system having a primary run and a trim run, each run including an inlet coupled to a main gas supply line, a pneumatically actuated control valve positioned downstream of the inlet, a pneumatic pressure controller having variable deadband adjustment, and an outlet feeding into a gas supply line to the facility. The control valve of the primary run is preferably high-capacity, while the control valve of the trim run is low-capacity. Further, the system and method for controlling gas supply to the facility has a total flow capacity through the primary run and trim run to the facility being defined by CX, which is the total flow capacity of the primary run (CP) plus the total flow capacity of the trim run (CT), and an actual gas flow to the facility being defined by FX, which is the actual flow of the primary run (FP) plus the actual flow of the trim run (FT) and wherein FX is less than CX, CT is less than CP and FX is either stable, increasing, or decreasing based on a demand from the facility.
