Diesel engine emergency shutdown

A shut down valve (also referred to as SDV or Emergency shutdown valve, ESV, ESD, or ESDV) is an actuated valve designed to stop the flow of a hazardous fluid or external hydrocarbons (gases) upon the detection of a dangerous event. This provides protection against possible harm to people, equipment or the environment. Shutdown valves form part of a Safety instrumented system. The process of providing automated safety protection upon the detection of a hazardous event is called Functional Safety Shutdown valves are primarily associated with the petroleum industry although other industries may also require this type of protection system. ESD valves are required by law on any equipment placed on an offshore drilling rig to prevent catastrophic events like the BP Horizon explosion in the Gulf of Mexico in 2010.

valve background

Diesel Tech Industries Ltd. (DTI) is a Canadian-owned company that produces revolutionary shut-off valves for diesel engines. After we noticed the limitations of existing shut-off systems, we developed a system that will safely shut off engines before they cause damage.


We've offered our DTI Guardian Shutdown System since 2005. We don't just sell these valves to truck owners across the country, but we also develop and manufacture them at our facility.


We are a division of the diesel repair business Diesel Tech Truck Repair Ltd., which has operated in Edmonton since 1999. We are owned and operated by a certified diesel engine specialist, Darren Rivet, who has worked in the field for more than 30 years..

As a truck owner, you want to protect your investment with the highest quality shutdown valve. If you don't, airborne hydrocarbons (often caused by fuel spills) can cause your diesel engine to enter into a "runaway state." This state can cause your engine to explode or catch fire, which can kill or injure truck drivers, destroy trucking equipment, and damage the environment.


At DTI, we've developed the ultra-modern DTI Guardian Shutdown System. This unique shutdown valves system monitors your engine's RPM. If the RPM reaches dangerous levels, the system shuts off the engine's air supply and safely and efficiently prevents dangerous engine explosions.


Our system not only protects operators from Edmonton and around the world from death and injury, but it will also protect against costly damage. It will also protect you from litigation due to property loss or environmental destruction.
