Ball valve - direct, 1/2" F x 1/2" F

Product detailed description

This ball valve is commonly installed in gas distribution systems for commercial and industrial buildings where fire safety is critical. Installers working with gas lines will find it suitable for use in boiler rooms, gas storage areas, and HVAC systems where automatic shut-off in case of fire is required. The valve ensures secure and reliable flow control while integrating a passive fire protection feature to prevent gas leakage during elevated temperatures.

The valve is designed for use in low-pressure gas systems and is intended for permanent installation in enclosed or semi-enclosed environments. It is typically used in conjunction with gas meters, regulators, and combustion appliances. The compact design allows for installation in tight spaces, and the direct flow path minimises pressure loss. The internal threading on both ends facilitates straightforward integration into existing piping layouts.

Technical parameters

Material	Nickel-plated brass CW617N Note
Operating temperature	-20 °C
Nominal pressure	PN 5
Weight	0.549 kg
Code	G2T106C00
Brand	IVAR

The operating temperature range of -20°C to +60°C makes this valve suitable for ambient conditions typical of indoor gas installations. The nominal pressure rating of PN 5 indicates it is appropriate for low-pressure gas systems. The fire shut-off mechanism activates at approximately +100°C, closing the flow path to prevent gas escape in the event of a fire. These parameters are essential when selecting the correct valve for a specific application and ensuring compliance with local regulations.

Installation and connection

To install the valve, ensure the pipeline is clean and free from debris. Use a suitable wrench to tighten the internal female threads (FF) on both ends, making sure not to overtighten and damage the sealing surfaces. Verify that the valve is fully open before tightening to avoid binding. After installation, perform a visual inspection to confirm that the valve body is aligned and that the sealing surfaces are undamaged. Common mistakes include incorrect orientation of the valve and failure to check the integrity of the sealing surfaces prior to installation. Ensure that the valve is installed in a position that allows for easy access during maintenance. Always follow the manufacturer’s guidelines for torque specifications if available.

Compatibility and accessories

This valve is compatible with standard gas piping systems using 1/2 inch internal threaded connections. When installing, ensure that the connected piping and fittings also use FF threads to maintain a secure seal. Additional components such as pipe unions or gaskets may be required depending on the system configuration. No specific accessories are listed for this model, but it should be used in conjunction with standard gas line components.

Technical background for designers

The valve operates on a simple ball mechanism that allows full flow when open and complete shut-off when closed. The nickel-plated brass CW617N construction provides resistance to corrosion and wear in gas environments. The fire shut-off feature is an integral part of the valve body and does not require external power or controls. It is designed to respond passively to heat, ensuring rapid closure without user intervention. The valve is intended for use in low-pressure gas systems and should not be used in high-pressure or high-temperature applications beyond its rated parameters.

Service and operation

Routine inspection should include checking the valve for signs of corrosion or mechanical damage. Verify that the shut-off mechanism remains functional by testing the valve in a controlled environment if possible. There are no specified service intervals for this model, but periodic checks are recommended to ensure continued performance. In the event of suspected failure, the valve should be removed and inspected by a qualified technician.

Frequently asked questions

Can this valve be used in high-temperature gas applications?
No, the maximum operating temperature is +60°C. The fire shut-off activates at around +100°C, which is not suitable for continuous operation at higher temperatures.

Is this valve compatible with copper gas piping?
Yes, provided the copper piping has matching internal female threads (FF) and is properly sized for the 1/2 inch connection.

Can the fire shut-off function be reset after activation?
Once the fire shut-off mechanism has activated, it must be replaced with a new valve. The component is not designed for manual reactivation.

What is the expected lifespan under normal conditions?
There is no specific lifespan stated, but the valve is designed for long-term use in low-pressure gas systems with proper maintenance and inspection.
