Ball valve gas - corner, 1/2" FM - butterfly

Product detailed description

This corner ball valve is commonly used in residential and commercial gas distribution systems where a directional change in pipe routing is required. Installers typically encounter this component when fitting connections between gas meters, appliances or regulating stations. The compact design allows for integration into tight spaces, such as utility rooms, boiler houses and underfloor installations. Its butterfly-style handle provides a clear indication of open or closed status, aiding in system diagnostics and routine inspections.

The valve is suitable for low-pressure gas applications and is frequently found in domestic and light industrial settings. It is often installed in conjunction with flexible gas hoses or rigid copper or steel piping. The nickel-plated surface offers corrosion resistance and ensures long-term durability in environments where moisture exposure is possible.

Technical parameters

Installation and connection

The valve features a 1/2 inch female metric (FM) thread on both ends, allowing direct connection to standard gas piping. Prior to installation, ensure that the pipe threads are clean and free of debris to prevent leaks. Apply approved pipe sealant or PTFE tape to the male threads of the connected pipes. Align the valve in the correct orientation, ensuring that the flow direction matches the system layout. Verify that the butterfly handle is fully aligned with the pipe axis when open and perpendicular when closed for accurate operation.

Compatibility and accessories

This valve is compatible with standard gas piping systems using 1/2 inch FM threaded connections. It is typically used with rigid copper or steel piping and can also be paired with flexible gas connectors for easier routing around obstacles. For complete system functionality, additional components such as pressure regulators, filters or gas detectors may be required depending on the application. No specific accessories are required for installation, though proper sealing materials should be selected according to local standards.

Technical background for designers

The operating principle is based on a spherical disc inside the valve body that rotates to allow or block gas flow. The nickel-plated brass CW617N material provides high tensile strength and resistance to erosion and corrosion, ensuring long-term reliability. The valve integrates into gas systems by providing a directional change while maintaining a tight seal under pressure. Longevity and performance depend on proper installation, correct alignment, and regular inspection for signs of wear or leakage. Avoid over-tightening the connections to prevent damage to the sealing surfaces.

Service and operation

Periodic visual inspections are recommended to check for signs of corrosion, leakage or mechanical damage. Ensure that the handle operates smoothly and that the valve can be fully opened or closed without resistance. No scheduled maintenance is required for this model unless specified in the manufacturer’s documentation. In case of suspected leakage, isolate the system and inspect the connections for integrity. Replace the valve if any defects are detected to maintain system safety and efficiency.

Frequently asked questions

Can this valve be used in a horizontal gas line?
Yes, the valve is suitable for horizontal installations. Ensure that the butterfly handle is positioned for easy access and visibility.

Is this valve suitable for natural gas applications?
Yes, the nickel-plated brass construction and PN 5 rating make it appropriate for natural gas systems operating within the specified temperature range.

What is the minimum ambient temperature for operation?
The valve can operate in environments as low as -20°C, provided that the gas supply remains unfrozen and the system is properly insulated if necessary.

How should the valve be aligned during installation?
Align the valve so that the butterfly handle is parallel to the pipe when open and perpendicular when closed, to indicate the correct operational state clearly.
