Ball valve gas, 3/4" FF - lever

Product detailed description

Gas ball valves are essential components in gas distribution systems, particularly in residential and commercial buildings where gas is used for heating, cooking, or industrial processes. These valves are commonly installed in gas lines to isolate sections of the system for maintenance or to control the flow of gas. The IVAR.G 51 model is suitable for low-pressure gas applications and is designed for reliable operation in a range of environments.

Installers working on gas systems often encounter the need to replace or install valves in existing pipelines. The IVAR.G 51 is intended for use in systems where the medium is natural gas or propane and where the operating conditions require a valve with a PN 5 rating. The valve is designed for use in systems with internal female threads and is equipped with an internal lever for manual operation. It is important to ensure that the valve is compatible with the system’s pressure and temperature requirements before installation.

Technical parameters

The operating temperature range of -30 °C to +60 °C makes this valve suitable for use in cold environments, such as unheated utility rooms or outdoor installations. The PN 5 pressure rating indicates that the valve is designed for low-pressure gas systems, which is typical for domestic and light commercial gas applications. These parameters are critical for correct sizing and selection to ensure the valve functions safely and efficiently within the system.

Installation and connection

The IVAR.G 51 is designed for 3/4 inch internal female thread (FF) connections. Before installation, the installer should verify that the existing pipeline has the correct thread type and that the system pressure does not exceed the valve’s PN 5 rating. The valve should be installed in a position that allows easy access for operation and inspection. Common installation mistakes include incorrect thread alignment, which can lead to leaks, and failure to check for debris in the pipeline before fitting the valve. It is also important to ensure that the lever is positioned for easy access and that the valve is fully open or closed as required by the system design.

Compatibility and accessories

This valve is compatible with gas systems that use 3/4 inch FF connections and operate within the specified pressure and temperature ranges. It is typically used in conjunction with gas pipes, fittings, and other components that are part of the gas distribution system. No additional accessories are required for standard installation. Installers should ensure that all components in the system are compatible with the valve’s specifications to avoid operational issues or safety risks.

Technical background for designers

The IVAR.G 51 is a ball valve, which operates by rotating a spherical disc with a bore to either allow or block the flow of gas. The valve is constructed from nickel-plated brass CW617N, a material known for its corrosion resistance and durability in gas applications. The internal lever provides a mechanical advantage for easy operation, even in tight spaces. The valve’s design ensures a tight seal when closed and minimal pressure drop when open. The choice of material and construction ensures long-term reliability in gas systems, provided that the valve is installed correctly and operated within its specified parameters.

Service and operation

No specific service intervals are provided for this valve. However, regular visual inspections are recommended to check for signs of wear, corrosion, or leakage. The lever should be operated periodically to ensure smooth movement and to prevent seizing. If the valve shows signs of leakage or difficulty in operation, it should be replaced immediately. The valve should be kept clean and free from debris to maintain its performance and longevity.

Frequently asked questions

Can the IVAR.G 51 be used in water systems?
No, the IVAR.G 51 is specifically designed for gas applications. For water systems, a different model with appropriate pressure and temperature ratings should be selected.

Is the IVAR.G 51 suitable for outdoor installations?
Yes, provided that the installation is protected from direct exposure to weather and that the operating temperature remains within the specified range of -30 °C to +60 °C.

Can this valve be used with propane?
Yes, the IVAR.G 51 is suitable for use with propane, as it is designed for gas applications and operates within the required pressure and temperature ranges.

What is the maximum operating temperature for this valve?
The maximum operating temperature is +60 °C for gas applications. For water systems, the maximum temperature is +120 °C, but this valve is not intended for water use.
