Automatic vent valve - 3/8" IVAR.VARIA

Product detailed description

Automatic vent valves are essential components in heating systems to ensure efficient operation by removing trapped air. These valves are commonly installed in residential and commercial buildings, including multi-family homes, industrial facilities, and commercial heating systems. Installers often encounter issues such as system inefficiency, uneven heating, and noise caused by air accumulation. Correctly sized and installed automatic vent valves help maintain system performance and longevity.

In systems where air removal is critical, the IVAR automatic vent valve provides a reliable solution. It is typically installed on radiators, baseboard heaters, or at high points in the system piping. The valve operates automatically, eliminating the need for manual intervention once installed. This ensures consistent system performance and reduces the risk of air-related issues over time.

Technical parameters

Installation and connection

Installation of the IVAR automatic vent valve should be carried out according to the manufacturer's guidelines. The valve is designed for a 3/8 inch connection, typically using a threaded connection. It is important to ensure the valve is installed in the correct orientation, with the venting port facing upwards. Before installation, the system should be depressurised, and all connections should be checked for tightness to prevent leaks.

Common installation errors include incorrect orientation, which can prevent the valve from functioning properly, and using incompatible sealing materials. It is also important to avoid using the side plug for venting, as this is not designed for that purpose and can lead to damage or failure. After installation, the system should be repressurised and checked for leaks, and the valve should be tested to ensure it is operating correctly.

Compatibility and accessories

The IVAR automatic vent valve is compatible with standard heating systems using water as the heat transfer medium. It is typically used in conjunction with radiators, baseboard heaters, and other heating system components. No additional accessories are required for standard installation, but it is important to use appropriate sealing materials compatible with the valve's materials and the system's operating conditions.

Technical background for designers

The IVAR automatic vent valve operates based on the principle of differential pressure and buoyancy. When air accumulates in the system, it rises to the top of the valve chamber, where it is released through the venting port. The valve is designed to close automatically when the system is operating correctly, preventing water loss while allowing air to escape. The CW617N brass body provides good mechanical strength and resistance to corrosion, making it suitable for use in water-based heating systems. The valve's performance is influenced by factors such as system pressure, temperature, and the presence of impurities in the water.

Service and operation

Regular inspection of the IVAR automatic vent valve is recommended to ensure it is functioning correctly. This includes checking for leaks, verifying that the valve is in the correct orientation, and ensuring that no obstructions are present in the venting port. No specific service intervals are provided for this model, but it is advisable to inspect the valve during routine system maintenance. If the valve is suspected of malfunctioning, it should be replaced to maintain system efficiency and prevent air-related issues.

Frequently asked questions

Can the IVAR automatic vent valve be used in systems with higher operating temperatures?
No, the valve is rated for operation up to +120 °C. Use in systems with higher temperatures is not recommended as it may affect the valve's performance and longevity.

Is the side plug on the valve used for venting?
No, the side plug is not designed for venting. Attempting to use it for this purpose is not recommended and may result in damage to the valve.

Can the valve be installed in a horizontal position?
No, the valve must be installed with the venting port facing upwards to ensure proper operation. Horizontal installation may prevent the valve from functioning correctly.

Is the valve suitable for use with glycol-based heating systems?
There is no specific information provided regarding compatibility with glycol-based systems. It is recommended to consult the manufacturer's technical data sheet for confirmation.
