Rail Industry Component:
Kelso Technologies Inc.: Kelso Pressure Relief Valves

Kelso sells external high-flow and low-flow pressure relief safety valves for rail tank cars. Kelso's external design PRV uses constant force springs with much lower overhaul costs than helical spring models. Kelso PRVs are safer to handle in repair facilities, light weight with NO castings, and have a low profile. With no operating parts exposed to the tank car commodity, our valve is not prone to corrosion or clogging. Kelso's valve design allows complete visual inspection of all components at the loading station or in the field. www.kelsotech.com
