Electromagnetic threaded valve for heating gases - 6/4"; 500mbar; NC; aluminium IVAR.M16-RM

Product detailed description

This electromagnetic threaded valve is commonly used in residential and commercial heating systems to regulate the flow of heating gases such as natural gas, CO, and PB. It is typically installed in gas supply lines where automatic shut-off is required in response to a signal from a gas concentration detector or in the event of a power failure. The valve ensures safe operation by closing automatically when no power is supplied, making it suitable for applications where gas safety is a priority. It is often found in central heating systems, gas boilers, and industrial heating installations where reliable and secure gas control is essential.

The valve is designed for integration into systems that require remote control or automatic shut-off, such as those with gas leak detection or emergency power failure protocols. It is particularly useful in applications where manual override is required for maintenance or testing purposes. The valve’s normal closed (NC) function ensures that the system remains shut off in the absence of an electrical signal, providing an additional layer of safety in gas handling systems.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 6
Weight	1.864 kg
Code	CM06C008
Brand	IVAR

The operating temperature range of -20 °C to +60 °C allows for use in a wide range of environments, including cold storage facilities and outdoor installations. The nominal pressure rating of PN 6 indicates the valve is suitable for low-pressure gas systems. These parameters are essential for correct sizing and selection, ensuring the valve operates safely and efficiently within the system’s hydraulic and thermal conditions.

Installation and connection

The valve is connected using a 6/4 inch threaded connection, which must be carefully aligned with the corresponding pipe or fitting. Prior to installation, the system should be depressurised and the valve inspected for any visible damage. The manual override lever should be tested to ensure it operates smoothly and returns to the closed position when released. A common installation mistake is incorrect thread engagement, which can lead to leaks or improper sealing. It is important to use the correct sealing compound or gasket material to ensure a tight connection.

Compatibility and accessories

This valve is compatible with gas detectors and control systems that provide a 230 V signal for actuation. It is typically used in conjunction with gas-fired heating appliances and boiler systems. For installations requiring a different supply voltage, alternative models with 12 V or 24 V/50 Hz are available upon request. No additional accessories are required for standard installation, but it is recommended to verify compatibility with the control system before commissioning.

Technical background for designers

The valve operates using an electromagnetic coil that, when energised, opens the valve and allows gas to flow. When the power is removed, a spring returns the valve to the closed position. The body is made from cast aluminium, which offers a good balance of strength, corrosion resistance, and thermal conductivity. The IP65 rating ensures protection against dust and water ingress, making it suitable for use in environments with potential exposure to moisture. The valve’s integration into the system depends on the control logic of the gas detection system, and its performance is influenced by the stability of the power supply and the integrity of the sealing surfaces.

Service and operation

Regular visual inspections should be carried out to check for signs of wear, corrosion, or leakage. The manual override should be tested periodically to ensure it functions correctly. No scheduled service intervals are specified in the technical data. If the valve fails to open or close properly, the electrical supply and coil should be checked for faults. The valve should be replaced if the sealing surfaces are damaged or if the coil is no longer functioning.
