Faced arch 90° - N - 42mm IVAR.IVN70

Product detailed description

This stainless steel faced arch is commonly used in residential and commercial buildings for press-fitting connections in heating, plumbing, fire protection, and solar systems. Installers working on closed-loop systems require durable fittings that can handle thermal expansion and maintain tightness under varying loads. This component is particularly suited for applications involving hot water, steam condensate, and inert gases.

The 90° bend allows directional changes in straight runs of pipe and is sized for 42mm nominal pipe dimensions. Its robust construction ensures resistance to corrosion and mechanical stress during installation and long-term operation.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN70.42
Brand	IVAR

The nominal pressure rating of PN 16 indicates the maximum pressure the fitting can handle at reference temperatures. The minimum operating temperature of -20°C means it is suitable for cold environments but must be verified against the full temperature range in the technical data sheet for specific application conditions. These parameters guide system designers in selecting the correct components for safe and efficient operation.

Installation and connection

To install the IVN70.42, ensure the ends of the pipe are clean and free of burrs. Use a press tool compatible with the fitting’s dimensions to create a secure connection. The internal thread allows for additional downstream connections using standard threaded fittings. Check the alignment of the fitting before pressing to avoid misalignment that could compromise the seal. Common installation errors include improper pressing depth and failure to verify the sealing indicator after pressing.

Compatibility and accessories

This faced arch is compatible with other components in the IVAR.IVN70 series for seamless integration into press-fit systems. For threaded connections, use standard Rp3/4" adapters or valves of matching size. Ensure all components are part of the same press-fit system to maintain uniformity and reliability.

Technical background for designers

The fitting operates as a directional change in the pipeline and relies on the press-fit mechanism to form a hermetic seal. The stainless steel material resists corrosion and maintains structural integrity under thermal cycling. System performance depends on proper sizing and alignment during installation. Longevity is influenced by the quality of the press connection and environmental factors such as fluid pH and temperature fluctuations.

Service and operation

No regular maintenance is required for this fitting due to its sealed design. However, periodic visual inspections should be conducted to check for signs of leakage or mechanical damage. Ensure the sealing indicator remains intact after installation as a sign of successful pressing.

Frequently asked questions

Can the IVN70.42 be connected to press-fit pipes of the same size?
Yes, the fitting is designed specifically for 42mm nominal diameter press-fit pipes and forms a secure connection when properly pressed.

Is it suitable for use with hot water in solar systems?
Yes, provided the operating temperature does not exceed the maximum limit specified in the technical data sheet and the system is correctly sized for pressure and flow.

Can it be used in fire sprinkler systems?
Yes, the material and pressure rating make it suitable for use in sprinkler systems where stainless steel components are required for corrosion resistance.

What happens if the sealing indicator is not reached during pressing?
If the indicator is not engaged, the connection may not be fully sealed. Recheck the pressing depth and adjust if necessary according to the manufacturer’s guidelines.
