Regulating Fittings - Corner, 1/2" x 15,1

Product detailed description

Corner regulating fittings are essential components in the installation of heating and plumbing systems in residential and commercial buildings. These fittings allow for directional changes in piping layouts while maintaining control over flow rates and pressure distribution. Installers working with copper piping systems often use such fittings in underfloor heating circuits, radiators, and domestic hot water lines. When integrating these fittings, it is important to consider the overall hydraulic balance of the system to ensure even heat distribution and prevent overloading specific zones.

Proper installation requires attention to the alignment of the fitting with adjacent components and the correct preparation of the copper pipe ends. Soft capillary soldering is the standard method for connecting these fittings, which relies on the capillary action of molten solder to create a secure and leak-free joint. The nickel-plated brass construction provides resistance to corrosion and ensures long-term performance in wet and high-temperature environments.

Technical parameters

Installation and connection

Installers should ensure that the copper pipe is cut cleanly and deburred before insertion into the fitting. The fitting is then soldered using a low-temperature flux and lead-free solder suitable for potable water systems. The 1/2 inch thread on one side allows for connection to threaded components such as valves or manifolds. It is important to check that the solder joint is fully formed and that there are no gaps or voids. A common mistake is overheating the fitting, which can damage the plating and reduce its lifespan. Always allow the joint to cool naturally before pressurising the system.

Compatibility and accessories

This fitting is compatible with copper piping systems and is typically used alongside other IVAR DD 202 fittings and valves. For complete installation, additional components such as solder, flux, and copper piping may be required. Installers should also have a set of pipe cutting and deburring tools on hand. This model is not interchangeable with fittings designed for plastic or steel piping due to differences in connection methods and materials.

Technical background for designers

The operating principle of this fitting is based on its ability to maintain a consistent flow path while allowing directional changes in the piping layout. The nickel-plated brass CW617N offers good thermal conductivity and resistance to galvanic corrosion when in contact with copper. Its mechanical strength supports the structural integrity of the piping network. Designers should consider the fitting's pressure and temperature limits when planning system layouts, especially in areas with high thermal loads or fluctuating pressure conditions. Proper sizing of the fitting in relation to the rest of the system ensures efficient operation and minimises energy consumption.

Service and operation

During regular system inspections, technicians should visually check the solder joints for signs of leakage or degradation. There are no scheduled maintenance intervals for this component due to its passive nature and lack of moving parts. In the event of suspected leaks, the system should be depressurised and the affected area inspected. Any damaged fittings should be replaced following the same installation procedure to restore system integrity.

Frequently asked questions

Can this fitting be used in a domestic hot water system?
Yes, the fitting is suitable for use in hot water systems due to its maximum operating temperature of +120 °C and compatibility with copper piping.

Is it possible to connect this fitting to a threaded valve?
Yes, the 1/2 inch thread allows for direct connection to threaded valves or other threaded components.

What type of solder is recommended for installation?
Lead-free solder suitable for potable water systems should be used to comply with health and safety regulations.

Can the fitting be used in a closed-loop heating system?
Yes, provided the system operates within the pressure and temperature limits specified in the technical parameters.
