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.

Rollover Protection


DTI’s latest technology integrates multiple inclinometers that measure the device’s angle in real-time.


If the vehicle starts to tip (and exceed the custom-set safe angles), the Guardian Safety System will automatically shut off your engine.


This means that damage to your equipment is minimized and further repair costs are avoided.

Handheld RF Remote Control


The Elite and Premium Guardian Safety Systems use a handheld remote which has a radio frequency key fob that allows the operator to start or shutdown their equipment remotely whenever needed.


This is particularly relevant to fracking and refueling applications as operators are often away from their engine.

Master Shutdown Capability


The Guardian Master System can save lives and equipment by instantly and simultaneously shutting down all diesel engines (equipped with Elite and Premium DTI Valves) in a pre-defined area.


This is the safest and quickest method of minimizing losses if an incident occurs and can save your company significantly on costs.
