Straight brass ball valve for distributor with screwing 1" + thermometer 0°C - 80°C, BLUE butterfly

Product detailed description

This straight brass ball valve is specifically designed for integration with heating distributors in residential and commercial buildings. It is commonly used in hydronic heating systems where individual circuits need to be isolated for maintenance, balancing, or temperature monitoring. The valve is installed in the return line of a distributor, allowing technicians to close off a single circuit without affecting the rest of the system. The built-in thermometer provides real-time temperature readings of the return water, which is essential for verifying heat transfer efficiency and system performance.

Typical applications include underfloor heating systems, radiator circuits, and other multi-loop heating configurations. The valve is installed in the same plane as the distributor body, ensuring a compact and organized layout. The blue handle serves as a clear visual identifier for return line circuits, preventing confusion with supply line components. This helps maintain correct system operation and facilitates troubleshooting.

The valve is constructed from brass, a material known for its durability and resistance to corrosion in water-based systems. The 1 inch threaded connection ensures compatibility with standard piping in heating systems. The thermometer range of 0°C to 80°C is suitable for typical heating return temperatures. These parameters are essential for correct sizing and selection, ensuring the valve can handle the expected flow rates and temperature conditions in the system.

Installation and connection

The valve is installed by screwing it into the distributor body using the 1 inch threaded connection. It is important to ensure that the threads are clean and free from debris before installation to prevent leaks. A sealing compound or thread tape should be applied to the male threads to create a watertight seal. The valve should be aligned in the same plane as the distributor to maintain a neat and accessible layout. Common installation mistakes include incorrect thread orientation, failure to use sealing materials, and over-tightening, which can damage the threads or the valve body. After installation, the system should be checked for leaks by pressurizing the circuit and inspecting the connection points. The blue handle should be clearly visible to indicate its function in the return line.

Compatibility and accessories

This valve is compatible with standard heating distributors that have a 1 inch threaded port for return line components. It is typically used in conjunction with supply line ball valves of the same type but with a red handle. No additional accessories are required for installation, as the valve is designed for direct connection to the distributor. When planning a system, it is important to ensure that the distributor has the correct number of ports for both supply and return valves to accommodate all circuits.

Technical background for designers

The valve operates on a simple ball valve mechanism, where a spherical disc with a bore allows or blocks the flow of water through the circuit. The brass construction provides good resistance to corrosion and thermal expansion, making it suitable for long-term use in heating systems. The built-in thermometer is integrated into the valve body and provides an accurate indication of the return water temperature, which is important for system balancing and performance analysis. The valve is designed to be installed in the return line of a heating circuit, where it can be used to isolate the circuit for maintenance or to adjust flow rates. The blue handle is a standard color code for return lines, helping to prevent misconnections during installation or service. The valve's compact design allows it to be installed in tight spaces, making it suitable for use in panel-type distributors or wall-mounted systems.

Service and operation

The valve requires minimal maintenance due to its simple design and robust construction. It should be inspected periodically for signs of leaks, corrosion, or wear on the handle. The thermometer should be checked for accuracy and replaced if it becomes damaged or unreliable. No specific service intervals are provided in the technical data, but routine visual inspections are recommended as part of standard system maintenance.

Frequently asked questions

Can this valve be used with a 1 inch threaded distributor port?
Yes, the valve is designed for a 1 inch threaded connection and is compatible with standard distributor ports of the same size.

Is the thermometer suitable for monitoring return water temperatures in a heating system?
Yes, the thermometer has a range of 0°C to 80°C, which is appropriate for typical return water temperatures in heating systems.

Can the blue handle be replaced with a different color?
No, the blue handle is a fixed part of the valve and cannot be changed. It is used to indicate that the valve is for the return line.

Can this valve be used in a system with multiple circuits?
Yes, the valve is designed for use in multi-circuit heating systems and can be installed on each return line to allow individual circuit isolation.
