Electromagnetic threaded valve for heating gases - 2"; 500mbar; NC; aluminium IVAR.M16-RM

Product detailed description

This electromagnetic valve is commonly used in residential and commercial heating systems where gas is the primary medium. It is typically installed in systems that require automated control of gas flow, such as central heating units, gas-fired boilers, and industrial gas heating applications. The valve is designed to respond to signals from gas concentration detectors or to shut off automatically in the event of a power failure. Installers working in HVAC and industrial environments will find this valve suitable for applications requiring reliable and precise gas flow control.

The valve is particularly useful in systems where safety is a priority, such as in gas supply lines for heating appliances. It ensures that the gas supply is cut off in the event of a fault or emergency, preventing potential hazards. The normally closed (NC) configuration ensures that the valve remains shut unless an active signal is applied, making it ideal for use in safety-critical systems.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 6
Weight	2.17 kg
Code	CM07C008
Brand	IVAR

The operating temperature range of -20°C to +60°C allows the valve to function in both cold and moderately warm environments, making it suitable for a wide range of installations. The nominal pressure rating of PN 6 indicates that it is designed for low-pressure gas systems, typically found in residential and light commercial heating applications. These parameters are essential for determining compatibility with existing systems and for proper sizing during design stages.

Installation and connection

The valve is connected using threaded fittings, and the 2-inch nominal size must be matched with corresponding pipe and fittings. During installation, the technician should verify that the valve is compatible with the system pressure and that the electrical supply matches the required voltage (230 V, 50/60 Hz). A manual override feature allows for temporary opening of the valve when needed. Common installation errors include incorrect thread orientation, failure to align the valve with the flow direction, and neglecting to check the integrity of the electrical connections before commissioning.

Compatibility and accessories

This valve is designed to integrate with gas detectors and control systems that provide the necessary electrical signals for operation. It is compatible with natural gas, CO, and PB (propane-butane) mixtures. When ordering, ensure that the control system and power supply are compatible with the valve's specifications. No additional accessories are typically required for standard installation.

Technical background for designers

The valve operates using an electromagnetic actuator that opens the valve when energised. The cast aluminium body provides good corrosion resistance and mechanical strength, making it suitable for use in environments with fluctuating temperatures. The NC configuration ensures that the valve remains closed in the absence of power, enhancing system safety. The valve's integration into the system depends on the control logic of the gas detection and safety systems. Long-term performance is influenced by the quality of the electrical supply and the environmental conditions in which the valve is installed.

Service and operation

No specific service intervals are provided in the technical data. 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. The IP65 rating provides protection against dust and water jets, allowing the valve to be installed in environments with moderate exposure to moisture.

Frequently asked questions

Can this 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, but the standard version operates at 230 V.

Is manual opening possible during operation?
Yes, the valve includes a manual opening mechanism for temporary override, which is useful during maintenance or testing.

What happens to the valve during a power outage?
During a power failure, the valve remains in the closed position due to its normally closed (NC) configuration, ensuring system safety.

Can this valve be used in industrial gas systems?
Yes, the valve is suitable for use in industrial applications where gas is the medium, provided the system pressure and temperature are within the specified limits.
