Thermostatic balancing valve - for TV distribution - 1/2 "F; temperature control and mechanical BY-PASS IVAR.RTV B

Product detailed description

Thermostatic balancing valves are essential components in heating and sanitary systems where consistent temperature control is required. This model is commonly used in residential and commercial buildings with central heating systems, particularly in applications where thermal disinfection of TV circuits is necessary. Installers working on plumbing systems for hot water distribution will find this valve suitable for ensuring stable flow rates and temperatures, especially in systems where hygiene and thermal efficiency are critical.

The valve is typically installed in TV circuits to manage the flow of hot water and maintain a set temperature range. It is particularly useful in systems where periodic thermal disinfection is required to prevent bacterial growth. The mechanical BY-PASS allows for temporary redirection of flow during disinfection cycles, ensuring system integrity and safety.

Technical parameters

The material and temperature range are key factors in selecting this valve for TV circuits. The CW617N brass construction ensures durability and resistance to corrosion, making it suitable for long-term operation in hot water environments. The temperature range of +35 °C to +60 °C is ideal for maintaining hygiene standards in hot water systems while preventing excessive energy consumption.

Installation and connection

Installation of the thermostatic balancing valve requires careful attention to the connection size and orientation. The valve features a 1/2 inch F connection, which must be securely tightened to prevent leaks. Before installation, ensure that the system is depressurised and that the valve is correctly positioned to allow for easy access to the BY-PASS mechanism.

Common installation mistakes include incorrect orientation of the valve, which can affect the performance of the BY-PASS function, and insufficient tightening of the threaded connection. Always verify that the valve is compatible with the existing system and that the flow direction is correct as per the manufacturer's instructions.

Compatibility and accessories

This valve is designed to integrate with standard TV distribution systems and is compatible with most hot water circuits that require temperature regulation. It is typically used in conjunction with other control and safety components such as pressure relief valves and circulation pumps. No additional accessories are required for basic operation, but system-specific components may need to be sourced separately.

Technical background for designers

The operating principle of the thermostatic balancing valve is based on a mechanical response to temperature changes. The valve is integrated into the system to maintain a constant temperature by adjusting the flow rate in response to variations in demand or ambient conditions.

The efficiency and service life of the valve are influenced by the quality of the installation, the stability of the system pressure, and the frequency of thermal disinfection cycles. Proper system design and regular maintenance are essential to prevent premature wear and ensure optimal performance.

Service and operation

Regular inspection of the valve is recommended to ensure that the BY-PASS mechanism functions correctly and that there are no signs of corrosion or leakage. The valve should be checked for proper operation during thermal disinfection cycles to confirm that the flow redirection is effective. No specific service intervals are provided in the technical data, but any visible damage or performance issues should be addressed promptly.

Frequently asked questions

Can the valve be used in systems with variable flow rates?
Yes, the valve is designed to adjust the flow rate in response to temperature changes, making it suitable for systems with variable demand.

Is the valve suitable for high-pressure TV circuits?
It is compatible with standard TV circuits, but it is important to ensure that the system pressure is within the manufacturer's specifications.

How is the BY-PASS function activated?
The mechanical BY-PASS is manually activated to redirect flow during thermal disinfection cycles, allowing for safe and effective system maintenance.

Can the valve be installed in a vertical position?
Yes, the valve can be installed vertically, but it is important to follow the manufacturer's guidelines for orientation and flow direction.
