Emergency Shut-Off Swing Check Valves (ESOV)-Image

Emergency Shut-Off Swing Check Valves (ESOV) are critical safety components designed to halt the flow of gas, liquid, or vapor in emergencies or hazardous conditions. The ESOV valves feature fusible links that react to high temperatures or fire by automatically closing the valve, thus stopping the flow and preventing further hazards. With the option for local or remote actuation, these valves provide flexibility in various industrial applications where safety is paramount.

The ESOV series offers ease of installation with ANSI flanged connections in sizes ranging from 2″ to 16″, and it is available in 150# and 300# ANSI standards. The valves are built to withstand temperatures from -20°F to 475°F, and their fire-safe fusible links ensure immediate closure during fire or high-temperature events. For engineers and safety professionals, these valves provide a reliable, cost-effective solution to mitigate risks associated with fluid, gas, or vapor systems.

By ensuring efficient flow control during hazardous conditions, ESOVs help engineers perform with greater confidence, ensuring the safety of personnel and equipment while reducing operational risks. With stringent factory testing to API 598 standards, these valves offer reliability and durability to support your system's safety requirements.
