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

Product detailed description

This ball valve is commonly used in residential and commercial gas systems to ensure safe operation in the event of a fire. Installers typically integrate it into gas distribution lines where automatic shut-off is required. The valve is suitable for both indoor and outdoor applications, provided environmental conditions remain within the specified temperature limits. Proper installation is essential to maintain system integrity and safety.

During installation, the valve serves as a critical component in gas line segmentation. It allows for manual control while providing automatic fire safety response. The internal threads make it compatible with standard pipe fittings, simplifying integration into existing or new systems. Installers must verify alignment and sealing to prevent leaks and ensure long-term reliability.

Technical parameters

Installation and connection

The valve connects via internal threads on both ends, which must be matched with corresponding fittings. Prior to installation, inspect the threads for damage and apply an appropriate sealing compound to ensure a tight seal. Ensure the valve is fully open before tightening to avoid misalignment. Common installation errors include over-tightening, which can damage the sealing surfaces, and improper orientation, which may interfere with the function of the firebag® mechanism.

Compatibility and accessories

This valve is designed for use with standard gas piping systems that utilise internal thread connections. No additional accessories are required for basic installation. However, it is recommended to use compatible sealing compounds and wrenches suited for brass fittings. No alternative or related products are available for this model.

Technical background for designers

The valve operates using a standard ball mechanism with a built-in firebag® device. In normal operation, the ball controls flow by rotating within the body. In the event of a fire, when ambient temperatures reach approximately +100°C, the firebag® activates to close the gas supply automatically. The nickel-plated brass body provides corrosion resistance and mechanical strength. The design integrates seamlessly into gas systems, with the firebag® enhancing overall safety without compromising flow efficiency.

Service and operation

Regular visual inspections are recommended to check for signs of wear, corrosion, or leakage. Ensure the valve remains fully operational by testing the opening and closing mechanisms periodically. There are no scheduled service intervals specified for this model. If the firebag® mechanism has been activated, the valve must be replaced, as it is a one-time-use safety device.

Frequently asked questions

Can this valve be used in high-pressure gas systems?
No, this model is rated for nominal pressure up to PN 5. Exceeding this limit may compromise the integrity of the valve.

Is the firebag® mechanism reusable after activation?
No, once the firebag® has been triggered, the valve must be replaced, as the mechanism cannot be reset.

Can the valve be installed in horizontal or vertical orientations?
Yes, the valve can be installed in either orientation, provided the connections are properly aligned and sealed.

What materials are used in the construction of the valve body?
The body is made of nickel-plated brass CW617N, offering good resistance to corrosion and mechanical stress.
