## Summary description

Shut-off flap valve Gazex MAG-3 DN50 is a mechanical shut-off device designed for pipeline isolation with nominal diameter DN50 and maximum operating pressure 0.5 MPa. The MAG-3 model features a flapped disk for rapid flow interruption, suitable for gas or liquid service where DN50 connections are required. Typical uses include industrial and utility pipelines, process lines and maintenance isolation.

## Long description

Shut-off flap valve Gazex MAG-3 DN50 is a mechanical shut-off device designed to isolate sections of pipeline with a nominal diameter of DN50 and a maximum operating pressure of 0.5 MPa. The MAG-3 model uses a flapped disk (butterfly-style element) to interrupt flow rapidly and provide a compact solution for both gas and liquid services in industrial and utility applications. The valve is supplied with DN50 flanged ends for straightforward installation into existing flange systems.
Advantages
The MAG-3 DN50 offers a simple mechanical design that enables quick operation and low maintenance needs. Its flapped disk construction provides fast shut-off and a small installation footprint compared with larger isolation devices. The flanged DN50 connections ensure compatibility with standard pipeline components while the rated pressure of 0.5 MPa covers many typical industrial and process line applications. Materials and construction are optimized for reliable mechanical performance under regular operating cycles.
Suitable for
 Isolation of gas distribution pipelines with DN50 connections
 Shut-off on process liquid lines and utility circuits
 Temporary or permanent section isolation during maintenance
 Industrial installations where compact, fast-acting isolation is required
Key specifications
 Nominal diameter: DN50
 Maximum operating pressure: 0.5 MPa
 Connection type: flanged ends for DN50
 Shut-off element: flapped disk (butterfly-style)
 Service media: suitable for gas and liquids (industrial/utility use)
 Operation: mechanical actuation for rapid flow interruption
How to use
Install the Gazex MAG-3 DN50 between matching DN50 flanges using appropriate gaskets and flange fastenings, ensuring correct alignment and bolt torque according to pipeline standards. The valve is operated mechanically to move the flapped disk to the closed position to stop flow and to the open position to restore flow. Perform leak checks after installation and follow routine inspection intervals to verify mechanical condition and flange integrity. Ensure the valve is used within its rated pressure limit of 0.5 MPa and that the selected materials are compatible with the specific gas or liquid in the system.
Usage recommendations
Use the valve for on/off isolation rather than fine flow control. For repeated cycling in abrasive or corrosive media, select compatible materials and schedule more frequent inspections. Always follow site safety procedures and pressure testing protocols when installing or isolating pipeline sections with the MAG-3 DN50.
