Shut-off Valves
Our expertly manufactured Shut-off Valves
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 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 a catastrophic explosion.
