FFD/FSD T-15 Flame Failure Gas Valve | Universal Safety Control for Appliances

Ensure the paramount safety of your gas appliances with the FFD/FSD T-15 Flame Failure Gas Valve. As a critical safety component, this robust and reliable gas control valve is designed to automatically shut off the gas supply if the pilot or main flame on your commercial cooker, oven, boiler, or other gas-fired appliance unexpectedly extinguishes. The T-15 valve provides essential protection against hazardous gas leaks, making it an indispensable part of any compliant and safe gas installation.

FFD/FSD (Flame Failure Device/Flame Supervision Device) valves like the T-15 are vital for meeting modern safety regulations. They continuously monitor the flame's presence, reacting instantly to any failure by isolating the gas supply, thus preventing dangerous unburnt gas accumulation and ensuring the well-being of occupants and premises.

Key Features & Benefits:

• Automatic Gas Shut-Off: Instantly cuts off the gas supply if the flame is lost, preventing dangerous gas leaks and ensuring operator and premises safety.
• Critical Safety Compliance: Essential for ensuring your gas appliances meet current safety standards and regulations.
• Reliable Flame Supervision: Features a durable mechanism that consistently monitors the flame, providing dependable protection.
• Universal T-15 Compatibility: Designed for broad use across a wide range of commercial gas appliances that utilise the common T-15 valve specification.
• Durable Construction: Built from high-quality materials to withstand the rigorous demands of commercial kitchens and industrial environments, ensuring a long service life.

Frequently Asked Questions (FAQs):

Q1: What is an FFD/FSD and why is it mandatory for gas appliances?

A1: An FFD (Flame Failure Device) or FSD (Flame Supervision Device) is a safety mechanism that automatically shuts off the gas supply if the flame on an appliance goes out. This is mandatory for safety as it prevents the dangerous buildup of unburnt gas, which could lead to explosions or carbon monoxide poisoning.

Q2: How does the T-15 valve detect flame failure?

A2: The T-15 valve typically works in conjunction with a thermocouple. The thermocouple is a small probe placed in the flame. When heated by the flame, it generates a tiny electrical current that keeps the gas valve open. If the flame goes out, the thermocouple cools, the current stops, and the valve immediately closes, cutting off the gas supply.

Q3: Is the T-15 a universal replacement?

A3: The T-15 is a common type, but you must always verify compatibility with your specific appliance's make, model, and existing valve. Check your appliance's service manual or consult a qualified gas engineer to confirm the correct part number and specifications (e.g., connection sizes, gas type, flow rates).

Q4: Can this valve be used for both Natural Gas and LPG?

A4: Yes, the FFD/FSD T-15 gas valve is designed for compatibility with both Natural Gas (NG) and Liquefied Petroleum Gas (LPG, which includes propane and butane).

Q5: What does "Manual Reset" mean for this valve?

A5: A "Manual Reset" means that once the valve has cut off the gas supply due to flame failure, it will not automatically reopen even if the flame returns. An operator must manually press a button or reset mechanism on the valve to restore the gas supply after the cause of the flame failure has been identified and corrected. This ensures safety by requiring human intervention.
