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

Product detailed description

This corner-mounted ball valve is designed for integration into low-pressure gas distribution systems. It provides a compact solution for directional flow control in domestic and commercial applications such as gas appliances, heating systems and metering points. The butterfly handle allows for quick shut-off and intuitive operation. The valve is particularly suited for tight spaces due to its angular configuration.

The valve is commonly installed in mechanical rooms, under sinks, or within wall cavities where space constraints require an angled connection. It ensures reliable sealing and minimal pressure loss in gas circuits. The nickel-plated brass body resists corrosion and wear, making it suitable for long-term service in indoor environments.

Technical parameters

Installation and connection

This valve features two internal thread (FF) connections of 1/2 inch nominal size. Prior to installation, verify that the pipeline is depressurized and clean to avoid debris entering the valve seat. Apply pipe thread sealant or PTFE tape to ensure leak-free connections. Tighten the fittings using an appropriate wrench, avoiding over-torque which can damage the brass threads.

Avoid cross-threading during assembly by aligning the male and female threads correctly. Check for full closure after installation by visually inspecting the handle position and performing a leak test. Incorrect orientation of the butterfly handle may lead to operational confusion during emergencies.

Compatibility and accessories

This model is compatible with standard gas piping systems using 1/2 inch internal thread connections. For secure mounting in confined areas, consider using a mounting bracket or pipe supports. Additional components such as union couplings or pipe clamps may be required depending on the layout and accessibility of the installation site.

Technical background for designers

The valve operates via a rotating ball with a central bore that aligns or blocks the flow path. The nickel-plated CW617N brass body provides high resistance to oxidation and mechanical stress, ensuring long-term durability. The butterfly handle design allows for rapid actuation and clear visual indication of open/closed status. The internal sealing surface must remain free of foreign particles to maintain tightness over time. System designers should account for the angular geometry when planning routing and clearance around the valve body.

Thermal expansion and vibration from adjacent equipment should be minimized through proper support and isolation. This helps preserve the integrity of the sealing mechanism and prevents premature wear of the metal-to-metal contact surfaces.

Service and operation

Periodic inspection of the valve should focus on the condition of the sealing surfaces and the integrity of the thread joints. Listen for unusual hissing sounds that may indicate leakage. Clean the exterior with a dry cloth to remove dust and contaminants. There are no scheduled service intervals specified in the technical documentation; however, any signs of operational stiffness or visible damage warrant immediate replacement.

Frequently asked questions

Can this valve be used in natural gas systems?
Yes, it is suitable for natural gas systems provided the operating pressure and temperature stay within the PN5 and -20°C to +60°C limits.

Is it possible to install this valve horizontally or vertically?
Both orientations are acceptable. Ensure that the butterfly handle is easily accessible and clearly visible for operation.

Can this valve be replaced with a standard straight-body ball valve?
No, the corner configuration is specific to this model. A straight-body version would not fit in installations requiring the angular layout.

What tools are needed for installation?
A standard pipe wrench and thread sealant are sufficient for assembly. Avoid using impact tools to prevent damage to the brass fittings.
