Vent valve IVAR.VARIA, 1/2", nickel

Product detailed description

Automatic air vent valves are essential components in heating systems, ensuring the efficient removal of air pockets that can reduce system performance and cause damage over time. These valves are commonly installed in residential, commercial and industrial buildings, particularly in systems where air accumulation is a known issue. Installers working on central heating systems, underfloor heating or hot water circuits will find these valves useful for maintaining system integrity and efficiency. The IVAR.VARIA model is suitable for systems where air removal is required without the need for manual intervention.

Proper installation of air vent valves is critical to their function. The valve must be positioned so that air can rise to the top of the system and be released through the vent. In larger systems, multiple valves may be required to ensure complete air removal. The IVAR.VARIA is designed for integration into such systems, providing reliable operation under standard heating conditions.

The nominal pressure of PN 10 and a maximum operating temperature of +120 °C define the conditions under which the valve can be safely used. These parameters are essential for correct sizing and selection, ensuring the valve can withstand the pressures and temperatures typical of heating systems. The brass CW617N material is suitable for long-term use in such environments.Installation and connection The IVAR.VARIA air vent valve is connected using a 1/2 inch thread. Installers should ensure that the valve is mounted in the correct orientation, with the venting mechanism at the top of the system. It is important to verify that the valve is not obstructed and that the system is free from debris before installation. A common mistake is attempting to use the side plug for venting, which is not designed for this purpose. The venting function must be carried out using the top screw only. Any manipulation of the side plug should be avoided to prevent damage to the valve.

Compatibility and accessories

The IVAR.VARIA air vent valve does not include a check valve (non-return valve). It is necessary to order a separate check valve to prevent backflow in the system. This valve is compatible with standard heating systems and can be used in conjunction with other IVAR components. When planning the system, ensure that all required accessories are included in the order to avoid delays during installation.

Technical background for designers

The IVAR.VARIA operates on an automatic principle, allowing air to escape while preventing the loss of water or other media. The brass CW617N material provides good resistance to corrosion and wear, making it suitable for use in heating systems. The design of the valve ensures that the venting mechanism is not in direct contact with the media or impurities, reducing the risk of clogging or failure. The integration of the valve into the system should take into account the flow dynamics and pressure conditions to ensure optimal performance and longevity.

Service and operation

The IVAR.VARIA requires minimal maintenance due to its automatic operation and sealed design. However, it is important to periodically check the valve for signs of wear or blockage. If the system shows signs of reduced efficiency or air accumulation, the valve should be inspected to ensure it is functioning correctly. No specific service intervals are provided, but regular visual inspections are recommended as part of routine system maintenance.

Frequently asked questions

Can the IVAR.VARIA be used in a closed-loop heating system?
Yes, the valve is suitable for use in closed-loop heating systems provided the operating conditions do not exceed the specified parameters of PN 10 and +120 °C.

Is a check valve required with the IVAR.VARIA?
Yes, the valve does not include a check valve. A separate non-return valve must be installed to prevent backflow in the system.

Can the side plug be used for venting?
No, the side plug is not designed for venting. Only the top screw should be used for air release. Manipulation of the side plug is not permitted.

What material is the valve body made of?
The valve body is constructed from brass CW617N, which provides good durability and resistance to corrosion in heating systems.
