The Fire-Safe Fusible Link Valve FSV-F Series is designed to automatically shut off or open flow during fires or in the presence of excessive heat. This valve is an essential safety component in systems handling flammable liquids or gases, ensuring rapid shut-off to prevent escalation of hazardous situations.

Key Features:

1. Automatic Operation in Fires:
   Equipped with fusible links that melt at predetermined temperatures (165°F / 74°C, 212°F / 100°C, and other options), causing the valve to shut off flow.

2. Durable Construction:
   Made from materials such as A216 WCB, A216 WC6, A352 LCB, A351 CF8, A351 CF8M, A351 CF3M, and A351 CF3, ensuring long-lasting performance under extreme conditions.

3. Valve Body Types:
   Available as Ball or Butterfly valves, with multiple connection options:

   • Ball Valve: Threaded, Welding, Flanged
   • Butterfly Valve: Wafer, Flanged, Lugged

4. Application Versatility:
   Suitable for a wide range of media including Ammonia, Gas, Liquefied Gas, Methanol, Fuel Oil, and other combustible gases and liquids.

Technical Specifications:

• Size: 1/2″ (DN15) to 12″ (DN300)
• Pressure Class: ANSI 150-300LB, PN16-PN64
• Body Materials: Carbon Steel, Stainless Steel, Lining Fluorine
• Fusing Temperatures: 165°F (74°C), 212°F (100°C)

Signal Switch Feedback Device:

The FSV-F Series is equipped with a limit switch feedback device that indicates valve open/close status. Its compact design allows for easier installation with actuators, and it supports local and remote monitoring functions, enhancing the overall safety system.

Application and Maintenance:

• Application Medium: Suitable for Ammonia, Gas, Liquefied Gas, Methanol, Fuel Oil, and various other combustible gases and liquids.
• Testing & Maintenance Precautions:
  To ensure functionality, it is recommended to manually open and close the valve at least three times a year. This prevents buildup of debris and ensures proper function in emergencies. During maintenance, ensure upstream valves are turned off to avoid accidental operation.
