Shuangda Valve (SDV) Company Emergency Shut Down Valves (ESDV, ESD, ESV, SDV) are used to isolate pressure and flow from a particular source during an overpressure situation or detection of a dangerous event. ESD valves are integrated into the design of the plant system equipment and can be installed in-line to any location upstream, midstream or downstream. • Immediate control of overpressure, high liquid level or both with integrated design • Integrated control panel by FTV • Pneumatically or hydraulically operated • Upstream installation flexibility due to connective design The emergency shutdown function is always performed by an emergency shut down valve. An emergency 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 upon the detection of a dangerous event. This provides protection against possible harm to plant team, equipment or the environment. ESDV 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 which FTV has pioneered for the last three decades. FTV offers a wide family of shutdown valves, actuators and positioners are engineered to prevent catastrophic incidents when deviations in critical processes occur. Our product lines cover a breadth of SIL, ANSI and DIN class ratings, providing solutions reliable enough to handle the most critical oil & gas applications, whether onshore, offshore or processing. Shutdown valves are primarily associated with the petroleum industry although other industries also require this type of protection system (power generation, chemical industry…).
Emergency shut-off valves, also known as emergency shutdown valves (ESDV) or emergency isolation valves, are critical safety devices used in various industrial and commercial applications to quickly and automatically shut off the flow of fluid or gas in the event of an emergency. These valves are typically installed at critical points in a system, such as at the point where a fluid or gas enters a facility or where it is transported to another location.
In the event of an emergency, such as a fire, earthquake, or other catastrophic event, emergency shut-off valves are designed to automatically close and prevent the release of dangerous fluids or gases that could cause damage to the facility or harm to personnel. This is achieved through a variety of different activation mechanisms, such as pressure sensors, temperature sensors, or other detection devices, which are connected to the valve and trigger its closure when an emergency is detected.
Emergency shut-off valves can be actuated by pneumatic, hydraulic or electrical actuator depending on the application and type of the valve. For example, in a pneumatic actuated valve, compressed air is used to actuate the valve, while in an electric actuated valve, an electric signal is used to open or close the valve.
The use of emergency shut-off valves is particularly important in industries such as oil and gas production, chemical processing, and power generation, where the release of dangerous fluids or gases could cause serious damage or injury. For example, in an oil and gas production facility, an emergency shut-off valve can be used to quickly shut off the flow of oil or gas in the event of a leak or other emergency, preventing the release of dangerous fluids that could cause a fire or explosion. Similarly, in a chemical processing facility, emergency shut-off valves can be used to quickly shut off the flow of dangerous chemicals, preventing the release of toxic gases that could harm personnel or the environment.
In addition to preventing the release of dangerous fluids or gases, emergency shut-off valves also play a crucial role in minimizing the potential for damage and injury in the event of an emergency. For example, in a power generation facility, an emergency shut-off valve can be used to quickly shut off the flow of coolant to a damaged turbine, preventing further damage and minimizing the potential for injury to personnel.
Despite their critical importance, emergency shut-off valves require regular testing and maintenance to ensure they are functioning properly. This includes testing the valve’s opening and closing time, checking for leaks, and ensuring that the valve is properly lubricated. Regular maintenance can help to ensure that emergency shut-off valves will function correctly in the event of an emergency, minimizing the potential for damage and injury.
However, one should consider that emergency shut-off valves are often used in conjunction with other safety devices like pressure relief valves, flame arrestors, and rupture discs, in order to ensure safety and protection for the plant and personnel.
Furthermore, emergency shut-off valves are often required to meet specific industry standards and regulations. For example, the American Petroleum Institute (API) has established standards for emergency shut-off valves used in the oil and gas industry. These standards cover design, testing, and maintenance requirements for emergency shut-off valves to ensure they meet safety and performance requirements.
In conclusion, emergency shut-off valves are a critical safety feature in industrial and commercial applications, helping to minimize the risk of accidents and reduce the potential for damage and injury. Regular testing and maintenance of these valves is essential to ensure they function properly in the event of an emergency. Emergency shut-off valves are an important component of a comprehensive safety system and are often required to meet specific industry standards and regulations.
