The Kimray Spring-Loaded Adjustable Back Pressure Regulator is a dependable, easy-to-operate solution for holding back pressure on an oil and gas vessel.
In this video, Mike explains how it works.
Why Use this Regulator?
The primary reason you would want to use the spring-loaded back pressure regulator over a pilot-operated regulator is that it requires no instrument gas. This means the valve releases no emissions.
Another advantage is you can flow liquid or gas or both simultaneously. For example, in a two-phase FWKO, it can regulate the oil and gas together, allowing the vessel to separate the water from these elements.
Other applications include heater treaters, central tank batteries, flash separators, and flares.
Here’s How it Works.
Process fluid enters the valve on the upstream side. It’s communicated up to the actuator chamber either internally through the stem or through an external tube depending on the model.
The upstream pressure creates a force on the diaphragm and diaphragm plate. When it overcomes the force of the spring, the valve opens.
This allows the upstream pressure to release downstream of the valve.
As the upstream pressure starts to fall below the spring set point, the valve closes.
The set point is controlled using the adjusting screw. To increase the set point, turn it clockwise; to decrease the set point, turn it counter-clockwise.
