Positive Air Shut Off Valve Systems: Diesel Tech Industries

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.

The DTI Guardian Shutdown System is unlike any positive air shut off valve system in the market today. With traditional shutdown systems operators have no way of determining why their Engine has stopped and once it has stopped, the valve is very difficult to be reset.

 

The system is designed so that the valve will not close unless users want their Engines to shutdown, whether it is by dash control, preset RPM shutdown or by key fob.

 

In our more advanced models, the DTI system records the status of the valve at the time of a shutdown and the butterfly design of the valve prevents the loading of unused fuel into the Engine when activated.

 

Equipped with "Intel-a-Valve Technology™" the Valve Control Unit (VCU) controller lets the user know the status of the valve through the LED light display and constantly monitors status of the positive air shut off valve system for any faults.

This enables a failure-free performance and makes it the only shutdown valve of its kind on the market.
