Emergency shutdown valves
These thermally activated Emergency Shutdown Valves (ESDs) are critical components in refinery, terminal and distribution safety systems. Thermal activated shutoffs work like fuses in the piping that carries extracted fuels. When a fire occurs, the fuel flow is shut down, preventing the fuel from feeding the fire. The thermally activated Emergency Shutdown Valves (ESDs) include: a fire-safe ball valve, a spring return pneumatic valve actuator, a heat activated pneumatic shutoff valve, a solenoid valve, and an optional manual override. These valves act as a local, automatic thermal shutdown in the event of fire.
