Electromagnetic flange valve for heating gases - DN 65; PN 6; NC IVAR.M16-RMP

Product detailed description

This electromagnetic flange valve is commonly used in industrial and commercial heating systems where reliable gas flow control is essential. It is typically installed in gas supply lines for heating applications such as boilers, furnaces, and heat exchangers. The valve ensures safe and precise control of gas flow, particularly in systems where automatic shut-off is required in response to gas leak detection or power failure. The normally closed (NC) configuration ensures that the valve remains shut in the absence of an electrical signal or during power outages, enhancing system safety.

Installation is typically carried out by heating engineers and service technicians in controlled environments such as mechanical rooms, boiler houses, and industrial facilities. The valve is designed for integration into systems that require remote control or automated response to gas leak detection. It is suitable for use with natural gas, carbon monoxide, and propane-based systems, depending on the application and system design.

Technical parameters

The nominal diameter (DN 65) and pressure rating (PN 6) are key parameters for determining the valve’s compatibility with the system’s piping and pressure requirements. The operating temperature range from -20°C to +60°C allows the valve to function in a wide range of ambient conditions. The IP65 rating ensures protection against dust and water jets, making it suitable for installation in non-enclosed areas.

Installation and connection

Installation requires a secure flange connection to the gas line, with the valve positioned for easy access to the manual override lever. The valve is supplied with a standard flange interface and must be connected using appropriate gaskets and bolts to ensure a gas-tight seal. The electrical connection is made via a 230 V, 50/60 Hz power supply, and the wiring must be routed in compliance with local electrical codes. During installation, it is important to verify the orientation of the valve (normally closed) and ensure that the control signal source (e.g., gas detector) is correctly wired. A common mistake is incorrect polarity or reversed signal wiring, which can prevent the valve from opening or closing as intended.

Compatibility and accessories

This valve is compatible with gas detection systems and emergency shutdown units that provide a control signal based on gas concentration. For full system functionality, it should be used in conjunction with a gas detector and a control panel capable of sending the required electrical signal. Additional components such as pressure regulators, filters, and flow meters may also be required depending on the system design. No related products are listed for this model.

Technical background for designers

The valve operates using an electromagnetic coil that, when energised, creates a magnetic field to open the valve. The normally closed configuration ensures that the valve remains shut until an electrical signal is applied. The body is made from cast aluminium, which provides good corrosion resistance and mechanical strength. The material is suitable for use in environments where exposure to gas and moderate temperatures is expected. The valve is designed to integrate into gas supply systems where automatic shut-off is required, and its performance is influenced by the stability of the power supply and the accuracy of the control signal source.

Service and operation

Regular inspection of the valve’s electrical connections and mechanical components is recommended to ensure reliable operation. The manual override lever should be tested periodically to confirm that it can be operated without resistance. No specific service intervals are provided in the technical data. During operation, the valve should be monitored for signs of wear, leakage, or failure to respond to control signals. If the valve fails to open or close as expected, the power supply and control wiring should be checked for faults.

Frequently asked questions

Can this valve be used with a 24 V power supply?
No, the valve is designed for 230 V operation. For 24 V applications, a different model must be selected.

Is the valve suitable for use with propane?
Yes, the valve can be used with propane-based systems, provided the system design and safety requirements are met.

Can the valve be manually opened during normal operation?
Yes, the valve includes a manual override lever that allows temporary opening without electrical input.

What is the maximum operating pressure of the valve?
The maximum operating pressure is 500 mbar, as specified in the technical data.
