Regulating fitting - corner, 3/4"

Product detailed description

Corner regulating fittings are commonly used in residential and commercial heating systems to control the flow of hot water. These fittings are typically installed in underfloor heating circuits, radiators, and other terminal units where precise flow regulation is required. Installers and technicians working on central heating systems will encounter these fittings during system balancing and maintenance. The fittings are designed for use with steel piping and must be selected according to the system pressure and temperature requirements.

When installing corner regulating fittings, it is important to ensure that the system is depressurised and that the fitting is compatible with the existing pipe material and diameter. The fitting must be securely tightened to prevent leaks and to maintain the integrity of the system. Incorrect installation can lead to flow imbalances or system failures, so careful attention to detail is required during the fitting process.

Technical parameters

Nominal pressure	PN 10
Weight	0.247 kg
Code	500655
Brand	IVAR

The material, nickel-plated brass CW617N, ensures good corrosion resistance and durability in hot water systems. The PN 10 pressure rating indicates that the fitting is suitable for systems operating at a nominal pressure of 10 bar. These parameters are essential for determining the suitability of the fitting for a specific application and for ensuring compatibility with the rest of the system components.

Installation and connection

The corner regulating fitting is designed for 3/4 inch connections, typically using male or female threads depending on the system configuration. Before installation, the threads should be cleaned and checked for damage. A thread sealant or PTFE tape should be applied to ensure a watertight connection. The fitting should be tightened evenly using a wrench to avoid over-tightening, which can damage the threads or the fitting body. Common installation mistakes include using incorrect thread types, failing to clean the threads, or not applying sufficient sealant.

Compatibility and accessories

This corner regulating fitting is compatible with steel piping systems and is intended for use in heating applications. It should be used in conjunction with other regulating components such as balancing valves and temperature sensors. No additional accessories are required for standard installation, but it is important to ensure that all components in the system are compatible in terms of pressure rating and material.

Technical background for designers

The corner regulating fitting operates by allowing controlled flow of hot water through the system. The nickel-plated brass construction provides good thermal conductivity and resistance to corrosion, making it suitable for long-term use in heating systems. The PN 10 rating ensures that the fitting can handle the typical operating pressures found in residential and commercial heating systems. The material properties of CW617N brass also contribute to the fitting’s ability to maintain a stable flow rate over time. The fitting is designed to integrate seamlessly into existing heating circuits and to provide consistent performance under varying load conditions.

Service and operation

Regular inspection of the fitting is recommended to ensure that there are no signs of leakage or corrosion. The threads should be checked for wear, and the fitting should be tightened if necessary. No specific service intervals are provided, but it is advisable to inspect the fitting during routine system maintenance. If any issues are detected, the fitting should be replaced to prevent further damage to the system.

Frequently asked questions

Can this fitting be used in systems with temperatures above 120°C?
No, the fitting is rated for a maximum temperature of +120°C. Use of the fitting in higher temperature systems is not recommended.

Is this fitting compatible with copper piping?
