Electromagnetic threaded valve for heating gases - 1/2"; without current closed IVAR.EVO

Product detailed description

This electromagnetic valve is commonly used in industrial and commercial heating systems where gas supply must be controlled based on external signals or in the event of a power failure. It is suitable for installation in boiler rooms, industrial gas lines, and other environments where gas safety is critical. The valve ensures that the gas supply is automatically cut off in the absence of power or upon receiving a signal from a gas concentration detector, making it a key component in gas safety systems. The valve is designed for use with natural gas, carbon monoxide, and propane, and is suitable for integration with automated control systems.

The 1/2 inch valve is compact and suitable for tight installation spaces. It is commonly used in systems where gas flow must be interrupted quickly and reliably. The valve is installed in the gas line and connected to a control system that monitors gas levels or power status. It is essential to ensure that the valve is correctly sized and installed to prevent leaks and ensure proper system operation.

The technical parameters define the valve's suitability for specific applications. The maximum operating pressure of 200 mbar and temperature range of -20°C to +60°C are critical for determining compatibility with the gas supply system. The 230 V AC power supply must be verified to match the control system's output. The normally closed configuration ensures that the valve remains shut in the absence of power or during a fault condition, which is essential for safety in gas handling systems.

Installation and connection

Installation of the IVAR EVO02008 requires a 1/2 inch threaded connection, typically using a male or female thread depending on the system configuration. The valve must be installed in a position that allows for easy access for inspection and maintenance. It is important to ensure that the valve is oriented correctly, with the flow direction marked on the body. The electrical connection must be made to a 230 V, 50/60 Hz power supply, and the control signal must be connected to a compatible gas detector or control unit. Common installation mistakes include incorrect orientation, failure to verify the power supply, and improper sealing of the threaded connection.

Compatibility and accessories

This valve is compatible with gas detection systems and control units that provide a 230 V signal. It is typically used in conjunction with gas detectors and safety switches that monitor gas levels or power status. No additional accessories are required for standard installation, but it is recommended to verify compatibility with the control system before installation. The valve is not compatible with low-voltage systems unless a version with 12 V or 24 V power supply is ordered separately.

Technical background for designers

The valve operates on an electromagnetic principle, where the solenoid is energized to open the valve and de-energized to close it. The brass OT 58 construction provides good resistance to corrosion and wear, making it suitable for gas applications. The valve is designed to integrate into gas safety systems where automatic shut-off is required. The service life and efficiency are influenced by the operating conditions, including the frequency of actuation and the quality of the gas being handled. The IP65 rating ensures that the valve is protected against dust and water ingress, making it suitable for use in harsh environments.

Service and operation

Regular inspection of the valve is recommended to ensure that the sealing surfaces are free from debris and that the electrical connections are secure. The valve should be tested periodically to verify that it opens and closes correctly in response to control signals. No specific service intervals are provided in the technical data, but it is advisable to follow the manufacturer's recommendations for maintenance. In the event of a fault, the valve should be disconnected from the power supply and inspected for signs of wear or damage.

Frequently asked questions

Can the IVAR EVO02008 be connected to a 12 V power supply?
Yes, the valve is available with a 12 V power supply option upon request. This version must be ordered separately and is not included in the standard 230 V model.

Is the valve suitable for use with propane?
Yes, the valve is suitable for use with propane as well as natural gas and carbon monoxide. The material and design are compatible with these gases.

What is the operating temperature range of the valve?
The valve is rated for operation between -20°C and +60°C, making it suitable for use in a wide range of environments.

Can the valve be used in a system with a 24 V control signal?
Yes, the valve can be used with a 24 V control signal, but the power supply must be compatible with the valve's 230 V rating. A version with a 24 V power supply is available upon request.
