M - valve - corner, 1/2" x EK

Product detailed description

This corner type M-valve is commonly used in residential and commercial heating systems where space constraints or piping layout require angled connections. It is typically found in systems utilising copper or multi-layer piping such as ALPEX, and connects to radiators or heating bodies with standard 1/2 inch internal thread. The nickel-plated brass construction ensures durability and corrosion resistance in wet and high-temperature environments. Installers should consider the nominal pressure and operating temperature when selecting components for system compatibility.

Technical parameters

Material	Nickel-plated brass CW617N
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.482 kg
Code	500831
Brand	IVAR

The PN 10 rating indicates suitability for low-pressure heating systems with a maximum working pressure of 10 bar. The operating temperature limit of +120°C means it can be used in standard central heating systems but not in high-temperature applications. The material specification (nickel-plated brass CW617N) ensures good mechanical strength and resistance to thermal expansion effects during long-term operation.

Installation and connection

To install, first verify that the pipe material matches the required push-fit fitting type (IVAR.TR for copper or IVAR.TA for ALPEX). The valve has a 1/2 inch internal thread for connecting to radiators or heating bodies. Ensure the mating threads are clean and free of debris before tightening. Common installation errors include using incorrect sealing compounds on the threaded connection or failing to secure the push-fit connection properly. After installation, perform a visual inspection to confirm all connections are secure and leak-free.

Compatibility and accessories

This valve is compatible with radiators that have a 1/2 inch internal thread connection. For push-fit installation, ensure IVAR.TR or IVAR.TA fittings are available depending on the pipe material. No additional accessories are required for standard installation. When designing a system, ensure all components share the same pressure and temperature ratings to maintain system integrity.

Technical background for designers

The valve operates as a control point for flow distribution in heating circuits. The nickel-plated brass body resists corrosion and maintains structural integrity under thermal cycling. Its PN 10 rating allows it to handle typical domestic heating pressures. Long-term performance depends on correct installation and avoiding over-tightening of threaded connections, which could cause stress fractures in the valve body. System designers should also account for thermal expansion in the piping layout to prevent mechanical stress on the valve.

Service and operation

Routine maintenance is not required unless system performance issues arise. During inspections, check for signs of leakage at both the push-fit and threaded connections. If the valve is removed for replacement, ensure the mating surfaces are clean and undamaged before reinstallation. No scheduled service intervals are specified in the technical documentation.

Frequently asked questions

Can this valve be used with copper pipe?
Yes, it is designed for use with copper pipe when connected using the appropriate IVAR.TR push-fit fitting.

Is it compatible with multi-layer piping systems?
Yes, it supports multi-layer piping such as ALPEX when using the IVAR.TA fitting.

Can it be used in high-temperature applications?
No, the maximum operating temperature is +120°C, making it unsuitable for high-temperature steam or industrial applications.

What type of thread does it have?
It features a 1/2 inch internal thread for connecting to radiators or heating bodies with standard threading.
