FM200 Extinguisher Check Valve is a critical component used in fixed fire suppression systems that operate with inert gases such as Argon, Nitrogen, and CO₂ mixtures. These valves are designed to control the flow of suppression agents during discharge while preventing backflow, ensuring system safety, integrity, and compliance.
This valve is built specifically for 80L to 140L cylinders operating at 200 and 300 bar, making it ideal for medium to large-scale gas suppression applications.
Compliance & Safety Standards
The FM200 check valve is:
- Designed in compliance with EN 12094 – the European standard for gas-based fire suppression components.
- Conforms to Directive 2014/68/EU – regarding the design and manufacture of pressure equipment within the EU.
- Manufactured for high-pressure inert gas cylinders to ensure leak-proof and reliable fire suppression performance.
Compatibility with Inert Gas Mixtures
This fire suppression check valve is suitable for all standard inert gas mixtures, including:
- IG-01: 100% Argon
- IG-100: 100% Nitrogen
- IG-55: 50% Argon, 50% Nitrogen
- IG-541: 52% Nitrogen, 40% Argon, 8% CO₂
These inert gases are naturally occurring in the atmosphere and have zero ozone depletion potential and no global warming impact, making them the preferred choice for eco-friendly fire protection systems.
Advantages of Using Inert Gas & Check Valves in Fire Suppression
Choosing an FM200 extinguisher check valve for an inert gas suppression system provides a range of advantages:
Environmentally Friendly
- Inert gases used (IG-01, IG-100, IG-55, IG-541) are naturally present in the atmosphere.
- Zero environmental impact, with no contribution to ozone depletion or global warming.
Safe for Sensitive Environments
- Ideal for protecting data centers, server rooms, archives, museums, labs, and telecommunication facilities.
- Does not damage sensitive electronic equipment, unlike water-based fire systems.
No Residue or Downtime
- Leaves no residue after discharge.
- Requires no cleanup, reducing operational downtime and enabling immediate recovery.
Fast & Efficient Fire Suppression
- Rapidly reduces oxygen concentration in the room below 15%, which is below the combustion threshold.
- Effectively extinguishes fires at their earliest stages.
