Vent valve - corner, 1/2"

Product detailed description

Corner vent valves are essential components in heating and plumbing systems where air accumulation can reduce efficiency and cause operational issues. This IVAR model is commonly used in residential and commercial buildings, particularly in systems where space constraints require angled fittings. Installers and technicians often encounter this type of valve in underfloor heating, radiators and central heating circuits. The corner design allows for installation in tight spaces without compromising functionality. The valve operates automatically, ensuring continuous air removal without manual intervention.

Correct selection and installation are critical to ensure the valve performs reliably over its service life. The 1/2 inch connection size is suitable for standard pipe diameters in heating systems, while the pressure and temperature ratings define the operating limits. This model is ideal for systems with moderate thermal loads and where air removal is a regular requirement.

The maximum operating temperature of +100°C makes this valve suitable for standard heating systems, including those with hot water circulation. The PN 10 pressure rating indicates that the valve is designed for low-pressure applications, such as residential and light commercial heating circuits. The nickel-chrome-plated brass CW617N material provides resistance to corrosion and ensures durability in wet environments. These parameters are essential for determining compatibility with the system and for proper sizing during design.

Installation and connection

The valve is installed using a 1/2 inch threaded connection, typically with BSP (British Standard Pipe) threading. Before installation, ensure the system is depressurised and the valve is oriented correctly to allow air to escape. A common mistake is incorrect orientation, which can prevent the valve from functioning. Always check the direction of flow indicated on the valve body. The threaded connection should be sealed with PTFE tape or suitable thread sealant to prevent leaks. After installation, perform a visual inspection to confirm the valve is securely fastened and aligned with the system.

Compatibility and accessories

This corner vent valve is compatible with standard heating systems that use 1/2 inch threaded connections and operate within the specified pressure and temperature limits. It is often used in conjunction with radiators, heat emitters and circulation pumps. For complete system integration, ensure that the valve is connected to a properly sized pipe and that the system includes adequate insulation and expansion components. No additional accessories are required for basic operation, but sealing materials should be selected according to the system's specifications.

Technical background for designers

The valve operates on a simple principle: internal components detect the presence of air and allow it to escape while preventing water loss. The nickel-chrome-plated brass body provides a balance of strength and corrosion resistance, making it suitable for long-term use in wet environments. The CW617N material is known for its mechanical properties and resistance to thermal expansion. When integrated into a system, the valve should be positioned at the highest point of the circuit to ensure effective air removal. The operating temperature and pressure limits are critical for ensuring the valve functions correctly and maintains system efficiency over time.

Service and operation

No regular maintenance is required for this valve, as it is designed for automatic operation. However, periodic visual inspections are recommended to check for signs of corrosion, blockage or leakage. If the valve is not functioning as expected, ensure the system is operating within the specified pressure and temperature limits. In the event of a blockage, the valve may need to be disassembled for cleaning. Always follow the manufacturer's guidelines for service procedures.
