Ball valve - corner, 1" M x 1" F

Product detailed description

Corner ball valves with fire shut-off mechanisms are essential components in gas supply systems, particularly in industrial and commercial applications. These valves serve as safety devices in the event of a fire, preventing gas leakage and reducing the risk of explosion. Installers working with gas systems often encounter the need to integrate such valves into new or existing infrastructure, ensuring compliance with safety regulations and system integrity.

The design of these valves allows for compact installation in tight spaces due to their corner configuration, which also helps reduce the overall footprint of the piping layout. They are commonly found in gas distribution systems, boiler rooms, and other areas where gas is stored or processed. Proper installation and alignment are critical to ensure the valve functions correctly under normal operating conditions and during emergency scenarios.

Technical parameters

The operating temperature range of -20°C to +60°C indicates the valve is suitable for environments with moderate thermal variation. The nominal pressure rating of PN 5 means it is designed for low-pressure gas systems. These parameters help in selecting the appropriate valve for specific system requirements and environmental conditions.

Installation and connection

Installation begins with verifying the correct dimensions and thread types of the connecting pipes. This model features male and female threads (MF) on the external and internal sides, respectively. Ensure the pipe ends are clean and free from debris before threading. Apply a suitable sealant to the male thread to prevent leaks. Use a wrench to tighten the connections securely, taking care not to overtighten and damage the threads or sealing surfaces.

Common installation mistakes include misalignment of the valve body, incorrect sealing methods, and failure to check for proper seating. Always confirm that the valve closes fully and opens smoothly after installation. A visual inspection of the connections for signs of leakage is recommended before commissioning the system.

Compatibility and accessories

This valve is compatible with standard gas piping systems using 1-inch threaded connections. For a complete installation, additional components such as sealing tape or pipe thread sealant may be required. No specific accessories are listed in the product description, so ensure all necessary fittings and tools are available before starting the installation process.

Technical background for designers

The operating principle of the valve involves a ball mechanism that controls the flow of gas. When the ambient temperature reaches approximately 100°C, the fire shut-off mechanism activates, closing the gas supply to prevent further leakage. The body is made of nickel-plated brass (CW617N), which offers good corrosion resistance and mechanical strength. This material choice supports long-term reliability in gas systems.

Integrating the valve into a larger system requires attention to the orientation of the valve and the positioning of the shut-off mechanism. The service life and efficiency depend on the quality of installation, the cleanliness of the system, and the absence of mechanical stress on the valve body. Regular inspections can help identify potential issues early.

Service and operation

No specific service intervals are provided in the product data. However, routine checks for signs of wear, corrosion, or leakage are recommended. Inspect the sealing surfaces and ensure the valve operates smoothly. In the event of any malfunction, the entire valve should be replaced rather than attempting repairs, as the integrity of the fire shut-off mechanism cannot be guaranteed otherwise.

Frequently asked questions

Can this valve be used in high-temperature environments?
The valve is rated for a maximum operating temperature of +60°C. It is not suitable for sustained exposure to higher temperatures beyond this limit.

What happens when the ambient temperature rises above 100°C?
The fire shut-off mechanism activates, causing the valve to close automatically and cut off the gas supply to prevent further leakage.

Is this valve compatible with other gas system components?
Yes, it is compatible with standard gas piping systems using 1-inch threaded connections. Ensure all components are properly aligned and sealed.

How is the valve secured during installation?
Use a wrench to tighten the male and female threaded connections. Apply a suitable sealant to the male thread before installation to prevent leaks.
