Electromagnetic threaded valve for heating gases - 5/4"; PN 6; NC; aluminium IVAR.M16-RM

Product detailed description

This electromagnetic valve is commonly used in residential and commercial heating systems where gas, carbon monoxide (CO), or propane-butane (PB) are the working media. It is typically installed in systems that require automated shut-off in response to signals from gas concentration detectors or in the event of a power failure. The valve is suitable for integration into central heating systems, gas-fired boilers, and industrial gas supply lines where reliable shut-off is essential for safety and system control.

As a normally closed (NC) valve, it ensures that the system remains shut off in the absence of an electrical signal or during a power outage. The manual override feature allows for temporary opening during installation, maintenance, or emergency situations. The valve is constructed from pressure-cast aluminium, which provides a lightweight yet durable solution for long-term operation in environments with fluctuating temperatures.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 6
Weight	1.96 kg
Code	CM05C0000008
Brand	IVAR

The valve is rated for a nominal pressure of PN 6 and can operate at a maximum pressure of 500 mbar. The operating temperature range is from -20 °C to +60 °C, making it suitable for both cold and warm environments. These parameters are essential for determining the correct valve size and type for the system. The PN 6 rating ensures compatibility with standard gas distribution systems, while the temperature range supports installation in both indoor and semi-outdoor locations.

Installation and connection

The valve is designed for threaded connections and features a 5/4 inch thread size. Before installation, ensure that the system is depressurised and that the valve is correctly oriented to match the flow direction. The manual override lever should be positioned for easy access. A common mistake during installation is incorrect thread alignment, which can lead to leaks or improper sealing. Always verify that the valve is fully tightened and that the sealing surfaces are free from debris. The IP65 rating allows for installation in environments with limited exposure to water or dust, but it is not suitable for fully submerged or high-humidity conditions.

Compatibility and accessories

This valve is compatible with gas detectors and control systems that provide a 230 V signal for actuation. It is intended for use with gas, CO and PB media and is suitable for integration into heating systems that require automated shut-off. No additional accessories are required for basic operation, but it is recommended to use a compatible mounting bracket for secure installation. No related products are available for this model.

Technical background for designers

The valve operates on an electromagnetic principle, where an electrical signal energises the coil, creating a magnetic field that opens the valve. The normally closed design ensures that the valve remains shut in the absence of power, enhancing system safety. The pressure-cast aluminium body is lightweight and corrosion-resistant, making it suitable for a wide range of environments. The integration into a system requires a reliable power supply and a compatible control signal. The service life of the valve is influenced by the quality of the electrical connections, the frequency of actuation, and the cleanliness of the working media. Regular inspection of the sealing surfaces and coil integrity is recommended to maintain performance.

Service and operation

The valve requires minimal maintenance due to its robust design and sealed construction. The manual override lever should be tested periodically to ensure smooth operation. No scheduled service intervals are specified in the technical data. During operation, it is important to monitor the power supply and ensure that the control signal is functioning correctly. In the event of a failure, the valve will remain in the closed position, preventing uncontrolled flow of gas or other media. Always verify the integrity of the electrical connections and the condition of the sealing surfaces during routine inspections.

Frequently asked questions

Can the valve be used with a 12 V or 24 V power supply?
Yes, the valve is available on request with 12 V or 24 V/50 Hz power supply options. The standard model operates at 230 V, 50/60 Hz.

Is the valve suitable for outdoor installation?
The valve has an IP65 rating, which provides protection against dust and water jets. However, it is not recommended for fully outdoor or submerged installations.

What is the maximum operating pressure of the valve?
The valve is rated for a maximum operating pressure of 500 mbar and a nominal pressure of PN 6.

Can the valve be manually opened and closed?
Yes, the valve includes a manual override lever that allows for temporary opening without electrical power. This is useful during installation or emergency situations.
