Back Pressure Regulator
The Gas Back Pressure Regulator is an integrated valve, meaning the valve body and pilot are one piece. Oil and gas producers use this regulator to hold pressure on production vessels.
This pressure creates the necessary force required to dump liquid out of the vessel and move it to the next process.
Common applications include oil and gas separators, heater treaters, and free water knockouts.
Pressure Reducing Regulator
A Pressure Reducing Regulator is used to reduce the pressure in a flow line.
You’ll often see the Pressure Reducing Regulator used as a suction controller or recirculation valve on compressors, or to supply fuel gas.
Liquid Back Pressure Regulators
If you are flowing liquid or extremely wet or dirty gas, you can use a Liquid Back Pressure Regulator.
You can use this regulator in a liquid back pressure application because it uses an outside source of supply gas (or air) to control the valve rather than the process gas.
