Ball valve - direct, 1/2" FM

Product detailed description

This direct ball valve is commonly used in residential and commercial gas systems where a reliable shut-off and fire safety feature are required. It is installed in gas supply lines to isolate sections of the system for maintenance or in the event of a fire. The valve is designed for use with flexible gas hoses and is suitable for applications where a compact, direct flow path is needed to reduce pressure drop and improve system efficiency. The internal FM thread allows for secure and leak-free connections to standard gas piping components.

Nominal pressure	PN 5
Weight	0.296 kg
Code	G2T100C00
Brand	IVAR

The operating temperature range of -20°C to +60°C ensures the valve functions in both cold and warm environments. The nominal pressure rating of PN 5 indicates the valve is suitable for low-pressure gas systems. These parameters are essential for correct sizing and selection to ensure the valve can handle the system's operational conditions without failure.Installation and connection To install the valve, ensure the system is depressurised and the piping is clean and free of debris. The 1/2 inch FM thread allows for direct connection to compatible fittings. The internal thread accepts a male fitting, while the external thread mates with a female fitting. Verify that the sealing surfaces are undamaged and apply a suitable sealing compound if required. A common mistake is incorrect thread orientation, which can lead to leaks or improper sealing. Always follow the manufacturer's guidelines for torque settings and sealing methods.Compatibility and accessories This valve is compatible with IVAR.FLEXIGAS flexible gas hoses and other standard gas system components with 1/2 inch FM connections. For complete system integration, ensure that all fittings and piping are rated for the same pressure and temperature conditions. Additional accessories such as sealing compounds and wrenches may be required for installation. Refer to the technical data sheet for full compatibility details.Technical background for designers The valve operates via a ball mechanism that rotates to open or close the flow path. The ball is seated within a body made of nickel-plated brass CW617N, which provides corrosion resistance and mechanical strength. The firebag feature is designed to melt at high temperatures, sealing the valve to prevent gas leakage in the event of a fire. The material properties ensure durability in gas environments and compatibility with common system materials. Proper integration into the system requires consideration of flow rates, pressure drops, and thermal expansion to maintain long-term performance.Service and operation Routine checks should include visual inspection for signs of wear, corrosion, or leakage. The sealing surfaces should be kept clean and free from debris to maintain a tight seal. The firebag should be inspected for damage or deformation that could affect its function. No specific service intervals are provided, but regular maintenance is recommended to ensure continued safe operation. In the event of a suspected failure, the valve should be replaced immediately.Frequently asked questions

Can this valve be used with natural gas systems?
Yes, the valve is suitable for natural gas systems provided the pressure and temperature conditions are within the specified range.

Is the firebag replaceable?
The firebag is an integral part of the valve and is not designed for replacement. If damaged, the entire valve must be replaced.

Can this valve be used in high-pressure gas systems?
No, the valve is rated for PN 5 and is not suitable for high-pressure applications beyond this rating.

What is the recommended sealing method for installation?
A suitable sealing compound should be applied to the threads to ensure a leak-free connection. Always follow the manufacturer's guidelines for sealing methods and torque settings.
