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

Product detailed description

This corner-mounted gas ball valve is commonly used in residential and commercial heating and plumbing systems. It provides reliable shut-off functionality in gas lines where space constraints require a compact, angled design. Installers typically use this valve in boiler rooms, under sinks, or in wall-mounted systems where a straight-line layout is impractical. The butterfly-style handle allows for quick and clear visual confirmation of the valve position, which is essential for safety and maintenance.

During installation, the valve is integrated into the gas line using male/female metric threads. The nickel-plated brass body ensures resistance to corrosion and wear, making it suitable for both indoor and semi-industrial environments. The operating temperature range from -20°C to +60°C makes it adaptable to a wide range of climates and system conditions.

Technical parameters

The pressure rating of PN 5 indicates that the valve is suitable for low-pressure gas systems. The operating temperature range from -20°C to +60°C means it can be used in both cold and moderately heated environments. These parameters are important for ensuring correct valve selection and system compatibility.

Installation and connection

Installers should ensure that the valve is correctly oriented with the butterfly handle in an accessible position for operation. The valve is connected using 1/2 inch male/female metric threads. Prior to tightening, the threads should be cleaned and checked for damage. Apply thread sealant or PTFE tape according to local standards to prevent gas leaks. A common mistake is over-tightening the connections, which can damage the sealing surfaces or cause thread stripping. After installation, the valve should be tested for leakage using appropriate methods such as soap solution or leak detectors.

Compatibility and accessories

This valve is compatible with standard gas piping systems using metric threaded connections. For installation, standard tools such as a wrench or spanner are required. Additional components such as sealing tape or thread sealant may be needed depending on the local installation practices and regulations. Installers should also consider the need for pipe supports or clamps to maintain alignment and reduce stress on the valve body.

Technical background for designers

The ball valve operates using a spherical disc with a bore aligned with the flow path. When the handle is rotated, the bore either aligns with the flow (open) or is perpendicular (closed). The nickel-plated brass CW617N material offers good mechanical strength and resistance to corrosion, which is essential for long-term performance in gas systems. The butterfly handle provides a clear indication of the valve's status. The valve's integration into a system depends on the flow rate and pressure requirements, and the operating temperature range ensures adaptability to different system conditions. The longevity of the valve is influenced by the quality of installation, the cleanliness of the system, and the absence of contaminants in the gas supply.

Service and operation

Regular inspection of the valve for signs of wear, corrosion, or leakage is recommended during routine maintenance. The butterfly handle should be checked for smooth operation and correct alignment. If the valve shows signs of gas leakage or difficulty in operation, it should be isolated and inspected for damage. No scheduled service intervals are specified in the technical data, but any issues should be addressed promptly to ensure continued safe operation.

Frequently asked questions

Can this valve be used in high-pressure gas systems?
No, this valve is rated for PN 5 pressure and is intended for low-pressure gas applications only.

Is it possible to install this valve in a vertical orientation?
Yes, the valve can be installed in any orientation as long as the butterfly handle remains accessible for operation.

What is the maximum temperature this valve can handle?
The maximum operating temperature is +60°C, beyond which performance and integrity may be compromised.

Can this valve be used with other types of fluids besides gas?
No, the valve is specifically designed for gas applications and should not be used with other fluids unless confirmed by the manufacturer's technical documentation.
