OUR EXPERTISE
Innovative equipment for ease and safety.
At Prism, we have been supplying innovative combustion solutions equipment to the oil and gas industry for over 35 years. Our longevity and extensive expertise have led to our innovative auto purge valve assembly solutions, bringing safety and ease to your load line applications.
When Prism Detonation Arrestor are not present in a flare line to prevent flash back, you run the risk of explosion. Our premier purge valves are designed to open the purge vent line, between the canister and the engine, to enable manifold vacuum to pull air through the canister and purge it of fuel vapors.

Why Auto Purge Valves?
Throughout our history, we have seen many incidents concerning air being drawn into storage tanks and underground knockout tanks. This condition can be very dangerous and costly, due to the accelerated corrosion and potential for internal explosions in the storage tank. The corrosion problems occur when air is continuously drawn into the tank while fluid is being removed. The risk of explosions occurs when air is being drawn into the tank as well, because with new environmental legislation, most vent lines are tied into a flare header where there is a continuous flame burning. As the air enriched gas stream travels out to the flare stack, at some time, the air/fuel mixture is stoichiometric and will support a back flash through the piping back to the storage tank.
Prism Auto Purge Valves
Don’t Let Mishaps Happen!
The unique combustion engineering of our Auto Purge Valve Assembly ensures that when the truck driver opens the load line valve to draw fluids from the storage tanks, a piggyback ball valve automatically opens to allow gas pressure to flow into the storage tank and displace the fluid being removed. As this gas pressure enters the tank and displaces the removed fluid, the air purge seal does not allow or require air to be pulled into the storage tank, thus eliminating corrosion and explosion problems. The key feature is that when the load line is opened, the displacement gas is automatically turned on for operator ease and safety.
