Ensure the paramount safety and compliance of your gas appliances with our essential Gas Safety FFD (Flame Failure Device) / FSD (Flame Supervision Device) Valve. This crucial push-button component is designed to automatically cut off the gas supply if a flame is extinguished, preventing dangerous gas leaks and providing vital protection for both commercial and domestic gas installations.
A Flame Failure Device (FFD) or Flame Supervision Device (FSD) is a mandatory safety feature on many gas appliances. It continuously monitors the presence of a flame at the burner. Should the flame be accidentally extinguished (e.g., by a draught, spill-over, or loss of gas pressure), this valve's advanced mechanism will automatically close, instantly stopping the flow of gas to that burner. This push-button variant requires manual re-ignition, ensuring a deliberate and safe restart procedure.
Investing in a reliable FFD/FSD valve is not just about compliance; it's about safeguarding lives and property by significantly reducing the risk associated with unmonitored gas flames.

Frequently Asked Questions (FAQs):
Q1: What is the primary function of an FFD/FSD valve?
A1: An FFD/FSD (Flame Failure Device/Flame Supervision Device) valve is a safety mechanism designed to automatically cut off the gas supply to a burner if the flame is unexpectedly extinguished, preventing the uncontrolled release of gas.
Q2: What is the difference between an FFD and an FSD?
A2: The terms FFD (Flame Failure Device) and FSD (Flame Supervision Device) are often used interchangeably to refer to the same safety function: monitoring a flame and shutting off gas if it fails. Some standards or manufacturers might use one term over the other, but their purpose is identical.
Q3: Who should install this gas safety valve?
A3: For safety and legal compliance, the installation, replacement, or servicing of any gas safety device like an FFD/FSD valve must only be carried out by a qualified and certified gas engineer. In the UK, this means a Gas Safe registered engineer.
Q4: How does the push-button mechanism work?
A4: The push-button mechanism requires you to physically press and hold a button to allow gas flow for ignition. Once the flame is established and the thermocouple (or similar sensing element) heats up, it signals the valve to stay open. If the flame goes out, the thermocouple cools, and the valve automatically closes, requiring another manual push-button press to re-ignite.
