Frequently Ask Questions
A Fire Safe Emergency Shut Down Valve (ESDV) is an emergency isolation valve designed to rapidly stop the flow of hazardous process media during situations such as fire, leakage, equipment failure or other emergency conditions.
A fire-safe valve is designed and tested to maintain an appropriate level of pressure-containing and shut-off performance after exposure to fire, according to the applicable fire-testing standard.
For this product, Alis Valves specifies API 607 / API 6FA fire-safe standards.
Alis Valves is a Fire Safe Emergency Shut Down Valve manufacturer and supplier in India, offering ESD valve solutions for oil & gas, refineries, petrochemical, chemical, power and other critical process industries. The current product range includes DN15–DN600, Class 150–900, pneumatic spring-return and electric fail-safe configurations, with API 607/API 6FA fire-safe options.
The primary purpose of an ESD valve is to isolate a hazardous process section quickly to help limit the release of process media and reduce the potential consequences of an emergency.
“Fire-safe” refers to a valve's ability to meet defined fire-test requirements. It does not mean that the valve is completely unaffected by fire or can operate indefinitely during a fire.
The applicable fire-testing standard and acceptance criteria should always be specified.
