Activated ESD Side Entry Trunnion Mounted Ball Valve Flange End WCB WCA

ESD Side Entry Trunnion Mounted Ball Valve

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 FireChek® heat activated pneumatic shutoff valve
• An solenoid valve
• A manual override (optional)

  Features & Benefits

• Local thermal shutdown for automatic shutdown in the event of fire
• Remote shutdown to isolate subsystems
• Valve assembly has normal process operating function until FireChek is triggered
• FireChek stops supply air to prevent feeding oxygen to the fire
