Regulating fitting - corner, 3/8"

Product detailed description

Corner regulating fittings are essential components in low-pressure heating systems where space constraints require directional changes in piping. These fittings are commonly found in residential and commercial buildings, particularly in underfloor heating, central heating distribution and small-scale industrial applications. They allow controlled flow redirection while maintaining system integrity and pressure balance. Proper selection ensures compatibility with existing pipe layouts and long-term operational reliability.

In installations involving steel piping, such as traditional radiators or panel heaters, these fittings help maintain consistent water flow and prevent turbulence. Installers often use them in conjunction with manifolds, balancing valves and thermostatic controls. Due to their compact design and robust construction, they are suited for concealed mounting behind walls or within floor slabs.

Technical parameters

Material	Nickel-plated brass CW617N
Nominal pressure	PN 10
Weight	0.135 kg
Code	500656
Brand	IVAR

The nominal pressure rating of PN 10 means the fitting is designed for use in systems with up to 10 bar operating pressure. This makes it suitable for most standard heating circuits. The temperature limit of +120°C defines its use in hot water systems but excludes steam or high-temperature applications. The material selection supports corrosion resistance and durability in wet environments.

Installation and connection

To install the corner regulating fitting, ensure the steel pipe ends are clean and free of burrs. Use a suitable pipe cutter to prepare the ends and apply a sealing compound if required by local standards. Connect using threaded fittings compatible with the 3/8 inch dimension. Verify alignment and secure tightening to avoid leaks. Common mistakes include overtightening, which can damage internal threads, or using incorrect sealing materials that may degrade over time.

Compatibility and accessories

This fitting is intended for direct connection to steel pipes in heating systems. When integrating into a manifold-based layout, ensure matching thread types and pipe diameters. Additional components such as pressure-reducing valves or temperature sensors should be selected according to system requirements. As no alternative or related products are listed, it is recommended to consult the manufacturer’s documentation for specific system configurations.

Technical background for designers

The nickel-plated brass CW617N provides a durable and corrosion-resistant base for the fitting. Its thermal conductivity supports even heat transfer along the piping network. The design allows for minimal flow restriction due to smooth internal geometry. System performance depends on correct placement relative to other control elements and adherence to hydraulic balancing principles. Longevity is influenced by water quality and chemical treatments in the system.

Service and operation

Routine inspection should focus on signs of leakage around the threaded joints and general corrosion. Ensure all connections remain tight and that the internal flow path remains unobstructed. No scheduled service intervals are specified in the provided data, so maintenance is typically carried out during system shutdowns or as part of broader inspections.

Frequently asked questions

Can this fitting be connected to copper piping?
No, it is specifically designed for steel pipe connections. Using it with copper may result in galvanic corrosion. Is this fitting suitable for steam systems?
No, the maximum operating temperature of +120°C limits its use to hot water heating systems. What is the recommended sealing method for installation?
Use a sealing compound compatible with brass and steel piping according to local regulations. Can this fitting be used in vertical piping runs?
Yes, provided the installation maintains proper alignment and does not subject the fitting to excessive bending forces.
