Kelso is a company with a bright future.
We have invented one of the most significant innovations in pressure relief valve technology in decades, our JS SRV.  Thanks to the many years of commitment and dedication of everyone involved with Kelso, we now have a line of pressure relief valves that can possibly provide a safer means of transporting and storing hazardous materials.

Kelso Technologies' unique, external JS75L (75 psi, low flow) pressure relief valve was specified for a new tank car build which began operations in North America in May of 2009, transporting motor oil for a large petroleum manufacturer.  This picture, as per regulation of the Association of American Railroads, shows how tank cars are required to specify a number of pieces of technical information by stenciling them on the side of rail tank cars.  On the upper left side of this tank car, Kelso's name appears indicating it is using the Kelso valve as its PRD (pressure relief device).
The physical valve, Kelso's JS75L, is shown in position in the upper right side of the picture, atop the tank car.
