Electromagnetic threaded valve for heating gases - 1"; PN 6; NC; brass IVAR.M16-RMO

Product detailed description

Electromagnetic valves are essential components in heating systems that require automated control of gas flow. This valve is commonly used in residential and commercial buildings where gas supply must be regulated based on signals from gas concentration detectors or in the event of a power failure. Installers working on gas supply lines for central heating systems, gas boilers, or industrial gas applications will find this valve suitable for integration into systems that require remote or automatic shut-off capabilities. The normally closed (NC) configuration ensures the valve remains shut when no power is applied, making it ideal for safety-critical applications where gas leakage must be prevented during power outages.

When installing this valve, the technician must ensure the system operates within the specified temperature range and pressure limits. The valve is designed to function in environments with ambient temperatures as low as -20°C, making it suitable for use in colder climates or unheated utility areas. The PN 6 rating indicates it can handle a nominal pressure of 6 bar, which is typical for low-pressure gas systems. The 1 inch thread size allows for compatibility with standard gas piping in many European installations.

The operating temperature range and material specification are critical for determining the valve’s suitability for a given installation. The brass body (OT 58) is chosen for its corrosion resistance and durability in gas environments. The PN 6 rating ensures the valve can handle typical low-pressure gas systems without failure. These parameters are essential for sizing and selecting the correct valve for the system’s pressure and temperature conditions.

Installation and connection

The valve is installed using a 1 inch threaded connection, which must be carefully aligned with the corresponding pipe. Prior to installation, the technician should verify the thread type and ensure that the sealing material is appropriate for gas applications. Common mistakes include using the wrong type of sealing compound or failing to check the integrity of the thread. The manual override feature should be tested after installation to confirm that the valve can be opened manually in case of an emergency. The IP65 rating ensures the valve is protected against dust and water jets, but the electrical connections must be made in a dry, secure location to prevent short circuits.

Compatibility and accessories

This valve is compatible with gas supply systems that use STN EN 161-compliant brass components. It is designed to work with gas detectors and control systems that provide the necessary electrical signal for valve actuation. Additional components such as pressure regulators or gas detectors may be required to complete the system. No specific accessories are listed for this model, but the technician should ensure that all electrical and mechanical connections are compatible with the existing system components.

Technical background for designers

The valve operates on an electromagnetic principle, where the solenoid coil is energized to open the valve. The normally closed configuration means the valve remains shut unless an electrical signal is applied. The brass body provides good resistance to corrosion and wear, making it suitable for long-term use in gas environments. The integration of this valve into a larger system depends on the control logic and the availability of a power supply. The service life of the valve is influenced by the frequency of operation, the quality of the electrical connections, and the environmental conditions in which it is installed.

Service and operation

No specific service intervals are provided for this model. However, 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. If the valve fails to open or close, the technician should check the electrical connections and the power supply. The IP65 rating ensures the valve is protected against environmental factors, but internal components should be inspected if the valve is exposed to extreme conditions.

Frequently asked questions

Can this valve be used with natural gas and propane?
Yes, the valve is suitable for use with natural gas (CO) and propane (PB) as specified in the product description.

Is the valve compatible with 12 V or 24 V power supplies?
Yes, the valve is available with 12 V and 24 V/50 Hz power supplies upon request, although the standard model operates at 230 V, 50/60 Hz.

What is the maximum operating pressure of the valve?
The maximum operating pressure is 500 mbar, which corresponds to a nominal pressure rating of PN 6.

Can the valve be manually opened in an emergency?
Yes, the valve includes a manual override feature that allows it to be opened manually when needed.
