Angle ball valve 3/4" with pressure nut

Product detailed description

This angle ball valve is commonly used in residential and commercial buildings for water supply lines and central heating systems. It provides reliable shut-off functionality in applications where space constraints require angled piping. The compact design makes it suitable for tight installation spaces such as under sinks, behind panels, or within wall cavities. Installers often use it to control flow in zones or to isolate sections of the system for maintenance.

The valve is particularly suited for use with copper or plastic pipes, where a secure and leak-free connection is essential. Its pressure nut allows for firm tightening during installation, ensuring a durable seal. The inclusion of two wingnuts in contrasting colours improves visibility and ease of operation during routine checks or adjustments. This makes the valve ideal for both permanent installations and temporary isolation points.

Technical parameters

Installation and connection

To install the valve, ensure the pipework is clean and free of debris before threading the valve into position. Use a wrench to tighten the pressure nut securely, but avoid over-tightening which could damage the sealing surfaces. Verify that the threads are properly aligned and that the valve body is positioned to allow for easy access to the wingnuts. A common mistake is failing to fully seat the valve against the pipe fitting, which can lead to leaks under pressure. After installation, perform a visual inspection and pressurise the system gradually to check for leaks.

Compatibility and accessories

This valve is compatible with standard brass and copper fittings used in central heating and water supply systems. To complete the installation, additional components such as pipe unions, coupling sleeves or pipe insulation may be required depending on the system layout. Ensure all components are made from compatible materials to prevent galvanic corrosion or mechanical failure over time.

Technical background for designers

The valve operates via a ball mechanism seated between two sealing surfaces. When the ball rotates, it aligns or blocks the flow path, allowing precise shut-off. The brass construction offers good resistance to corrosion and wear, making it suitable for long-term exposure to potable water and heating fluids. Proper integration into the system requires consideration of flow direction and pressure balance. The presence of two distinct wingnuts aids in identifying the open and closed positions, supporting efficient system diagnostics and maintenance.

Service and operation

During regular service checks, inspect the valve for signs of leakage around the threads and verify that the wingnuts remain functional. Ensure that the valve operates smoothly without stiffness or resistance. If the valve shows signs of wear or fails to close tightly, it should be replaced to maintain system integrity. Routine cleaning of the external surface may help prevent the accumulation of dirt or scaling in high-moisture environments.

Frequently asked questions

Can this valve be used in hot water systems?
Yes, it is suitable for use in both hot and cold water systems due to the properties of the brass material and sealing design.

Is the pressure nut sufficient for high-pressure applications?
The pressure nut provides a secure seal appropriate for standard pressure levels in domestic and light commercial settings, up to the nominal pressure rating specified.

Can the valve be used vertically or horizontally?
It can be installed in either orientation, but care must be taken to ensure the valve body is fully seated and the sealing surfaces are undamaged after installation.

What tools are needed for installation?
A standard adjustable wrench is typically required to tighten the pressure nut, while a screwdriver may be useful for loosening or adjusting the wingnuts during initial setup.
