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

Product detailed description

Gas corner ball valves are commonly used in residential and commercial gas distribution systems to provide directional control in confined spaces. Installers working on gas pipelines in kitchens, boiler rooms, or industrial settings often require valves that can fit around corners or obstacles. This type of valve allows for secure shutoff and directional flexibility while maintaining compliance with gas safety standards. When installed correctly, it ensures minimal pressure loss and reliable sealing.

For systems where space constraints prevent straight-line installation, corner valves offer a compact alternative to standard inline ball valves. They are particularly useful in retrofitting older systems or in new builds with limited access. Technicians should ensure that all connections are clean and free from debris before assembly to prevent leaks. The butterfly-shaped handle provides a clear indication of open or closed status and facilitates quick operation during maintenance or emergency shutdowns.

Technical parameters

Installation and connection

This valve features external male metric threads (MM) on both ends and is intended for direct connection to similarly threaded piping components. Installers should verify that the pipe threads are compatible and that the sealing surfaces are undamaged before tightening. A wrench or spanner should be used to secure the valve, ensuring even torque to avoid warping the body or damaging the seal. Common mistakes include over-tightening, which can cause thread stripping, and using incompatible sealing compounds, which may degrade over time. Always confirm that the system is depressurised before beginning installation.

Compatibility and accessories

This ball valve is designed to integrate with standard gas piping systems using 1/2 inch MM connections. It is typically used in conjunction with gas meters, regulators, and other shut-off devices. For a complete installation, additional components such as sealing tape or pipe thread sealant may be required to ensure leak-free connections. As no related products are specified, it is recommended to consult the technical data sheet for specific accessory requirements based on the system design.

Technical background for designers

The operating principle of a ball valve involves a rotating spherical disc with a through-hole that aligns with the flow path when open. The nickel-plated brass CW617N material offers good mechanical strength and resistance to chemical exposure in gas environments. The butterfly handle provides a visual and tactile confirmation of the valve position. The valve’s compact corner design allows for efficient routing of gas lines around obstacles or in tight spaces. The service life and performance depend on correct installation, regular inspection, and adherence to pressure and temperature limits.

Service and operation

During routine maintenance, technicians should inspect the valve for signs of leakage, corrosion, or physical damage. The butterfly handle should move smoothly without resistance, indicating that the internal mechanism remains functional. No scheduled service intervals are specified in the brief, but any irregularities in operation should prompt further investigation. The valve does not require lubrication under normal operating conditions. In case of suspected failure, the entire unit should be removed and replaced rather than repaired.

Frequently asked questions

Can this valve be used in high-pressure gas systems?
No, this valve is rated for nominal pressure up to PN 5 and is not suitable for high-pressure applications beyond this specification.

Is this valve compatible with non-metallic gas piping?
It is designed for metallic piping with matching external metric threads. Compatibility with non-metallic systems depends on the availability of suitable adapters or fittings.

Can the butterfly handle be replaced with another type?
No, the butterfly handle is an integral part of the valve and cannot be replaced separately. It is not designed for disassembly or modification.

Does this valve require a special sealing compound during installation?
No, standard pipe thread sealant or sealing tape is sufficient for ensuring a leak-free connection. Avoid using excessive amounts to prevent over-tightening and potential damage.
