Thermostatic relief valve - 6/4"; Kv 17; 55° C IVAR.TERMOVAR

Product detailed description

Thermostatic relief valves are essential components in solid fuel boiler systems where temperature control and system protection are critical. These valves are commonly installed in residential and commercial heating systems to manage excess heat and prevent damage to the boiler and associated components. Installers working with solid fuel boilers must ensure proper integration of these valves to maintain system efficiency and longevity.

In installations involving solid fuel boilers, the risk of low-temperature corrosion and soot accumulation is significant. Thermostatic relief valves help mitigate these risks by releasing excess heat when the system reaches a predefined temperature threshold. This prevents overheating and ensures the boiler operates within safe parameters. The 6/4 inch connection size is suitable for medium to large systems, making this valve appropriate for a range of applications.

Technical parameters

Installation and connection

Installation of the thermostatic relief valve requires careful attention to the connection size and orientation. The 6/4 inch connection is typically threaded and must be securely fastened to prevent leaks. Installers should verify the direction of flow and ensure that the valve is positioned to allow proper drainage of excess fluid. Common installation mistakes include incorrect orientation, which can lead to improper operation, and failure to check for debris in the piping, which can affect the valve's performance.

Compatibility and accessories

This thermostatic relief valve is designed to work with solid fuel boilers and associated heating systems. It is compatible with standard piping configurations and can be integrated with other system components such as expansion vessels and pressure relief valves. No additional accessories are required for basic installation, but system designers should ensure that the valve is part of a comprehensive protection strategy for the boiler and piping network.

Technical background for designers

The operating principle of the thermostatic relief valve is based on temperature-sensitive elements that respond to changes in system temperature. When the temperature reaches the set point of 55°C, the valve opens to release excess heat, preventing damage to the boiler and reducing the risk of corrosion. The integration of this valve into the system depends on the boiler's design and the overall heating strategy. Factors such as flow rate, system pressure, and thermal load must be considered to ensure optimal performance and longevity of the valve.

Service and operation

Regular inspection of the thermostatic relief valve is necessary to ensure continued performance. Installers should check for signs of wear, corrosion, or blockage in the valve's components. The valve's design allows for adjustment of the flow rate under pressure without the need for tools, which simplifies maintenance. No specific service intervals are provided, but periodic checks are recommended to ensure the valve functions correctly and safely.

Frequently asked questions

Can the thermostatic relief valve be used with other types of boilers?
While primarily designed for solid fuel boilers, the valve can be used with other boiler types if the system parameters match the valve's specifications. The operating temperature and pressure must be within the valve's rated limits.

How is the flow rate adjusted on this valve?
The flow rate can be adjusted under pressure without the need for tools. This feature allows for fine-tuning of the valve's performance to match the system's requirements.

Is the thermostatic insert replaceable?
Yes, the thermostatic insert is designed to be replaceable, allowing for maintenance and adjustment without replacing the entire valve body.

What is the maximum operating temperature of the valve?
The valve is rated for a maximum operating temperature of +120°C, which ensures compatibility with high-temperature boiler systems.
