flexible gas discharge hose with check valve is a critical component in modern clean agent fire suppression systems, particularly for systems using FM-200 (HFC-227ea) or similar gaseous extinguishing agents. Designed for durability, flexibility, and safety, this hose ensures efficient gas discharge from FM-200 cylinders to the manifold or piping network, while also preventing dangerous gas backflow.
Key Features of DN50 Flexible Gas Discharge Hose with Check Valve
Durable Construction
- The DN50 hose is reinforced with stainless steel mesh, providing high strength, flexibility, and corrosion resistance.
- Designed to withstand high-pressure discharge environments typical in gas suppression systems.
Integrated Welded Check Valve
- Comes with a built-in check valve, welded directly to the hose.
- Ensures one-way gas flow to prevent backflow or leakage during maintenance or discharge.
- Complies with TCVN 7161-1, regulation 6.2.4.4, which requires check valves in manifold systems with multiple cylinders.
Threaded Connections
- Threaded ends on both sides ensure easy, secure installation with minimal tools.
- Compatible with FM-200 discharge piping and manifold systems.
Easy Installation
- Can be installed horizontally or bent at a 90-degree angle, depending on system design.
- Compact and space-saving for tight installations.
Welded Fittings
- All joints are welded to enhance the overall integrity and leak-proof performance of the hose assembly.
Product Description
The DN50 flexible gas discharge hose with check valve is used to connect a 140L FM-200 cylinder to the discharge pipework or to a multi-cylinder manifold in fire suppression systems. Its flexibility and reinforced construction make it ideal for both small and large installations.
🔧 Material & Construction
- Hose Material: Stainless steel mesh reinforced
- Check Valve: Integrated and welded for maximum safety
- Fittings: Threaded, welded connections for durability and ease of use
🔄 Flow Control
- The check valve prevents reverse flow, which is crucial in multi-cylinder systems where gas loss during maintenance can lead to system failure or safety hazards.
Installation Instructions & Technical Specifications
📦 Installation Guidelines
- Install horizontally or at a 90° bend as per system layout.
- Ensure tight connections using appropriate threading tools.
- Verify the check valve direction before connecting to avoid flow issues.
