How Does the Kimray Dump Valve Work?

In this video, Product Manager Mike Fick demonstrates the operation of a Dump Valve.

The Kimray Lever-Operated Mechanical Dump Valve is a reliable, emissions-free product designed to dump liquid from oil and gas production vessels such as separators, treaters, and free water knockouts. Here’s how it works.    

How the Mechanical Dump Valve Works

A float inside a production vessel moves up and down based on the liquid level inside. This moves the lever on the Trunnion Assembly. This lever is mechanically linked to a lever on the Dump Valve by a linkage rod.

As the liquid level in the production vessel begins to rise, the float moves upward. This forces the trunnion lever downward. This pushes the valve lever down and opens the valve.

As the liquid level in the vessel begins to fall, the float moves downward, forcing the trunnion lever upward. This pulls the valve lever up and closes the valve.

There are two versions of this product. These are the Diaphragm Balanced and Piston Balanced Throttling. The illustration in the video shows the action of the Diaphragm Balanced version. This is a cost-effective version ideal for use in normal conditions.

The Piston Balanced Throttling version of the Dump Valve is an ideal option if your production conditions are more erosive. In this valve, the trim raises up out of the flow path when it opens. This limits its contact with the process fluid, thereby mitigating deterioration due to erosion.
