Mixing valve - three-way, 5/4"; Kv 12; 10 Nm

Product detailed description

This three-way mixing valve is commonly used in heating systems where precise temperature control is required. It is suitable for integration into central heating systems, underfloor heating circuits, and other applications where fluid mixing is necessary. The valve is designed for use in environments where the operating temperature can reach up to 120°C, making it suitable for high-temperature heating systems. The valve is typically installed in conjunction with a servomotor or actuator to enable automated temperature regulation.

Installers and system designers working on residential, commercial or industrial heating systems will find this valve suitable for applications requiring a Kv value of 12. The valve is designed to handle a nominal pressure of PN 10 and is constructed from brass CW617N, a material known for its durability and resistance to corrosion in hot water and heating environments. The valve is intended for use with compatible servomotors that provide a 10 Nm actuation torque.

The operating temperature limit of 120°C ensures the valve is suitable for high-temperature heating systems. The nominal pressure rating of PN 10 indicates the valve is designed for use in systems with moderate pressure levels. The 10 Nm torque requirement is important for selecting a compatible servomotor or actuator. The Kv value of 12 is used to calculate the flow capacity and to ensure the valve is correctly sized for the system.

Installation and connection

The valve is installed using standard 5/4 inch connections, which are typically threaded for secure and leak-free installation. Before installation, the installer should verify the thread type and ensure compatibility with the system piping. The valve should be mounted in a position that allows for easy access for maintenance and inspection. Common installation errors include incorrect orientation of the valve, improper sealing of the connections, and failure to align the valve with the actuator. It is important to follow the manufacturer's instructions for correct positioning and tightening of the connections.

Compatibility and accessories

This valve is designed to be used with servomotors or actuators that provide a minimum actuation torque of 10 Nm. The brass CW617N construction ensures compatibility with a wide range of heating fluids and system materials. When installing, it is important to ensure that the actuator is correctly aligned with the valve stem and that the electrical connections are compatible with the control system. No additional accessories are required for basic operation, but installers should verify the compatibility of the control system and actuator before commissioning.

Technical background for designers

The three-way mixing valve operates by allowing the mixing of two fluid streams to produce an output at a desired temperature. The valve is constructed from brass CW617N, a material that offers good mechanical strength and resistance to corrosion in hot water environments. The valve is integrated into the system using standard 5/4 inch threaded connections and is controlled via a servomotor or actuator. The service life of the valve is influenced by the operating conditions, including the temperature and pressure levels, as well as the quality of the installation and maintenance. The efficiency of the valve depends on the correct sizing and selection of the actuator and control system.

Service and operation

No specific service intervals are provided in the technical data. However, regular inspection of the valve and connections is recommended to ensure continued performance. Installers should check for signs of leakage, corrosion or wear on the valve body and connections. The actuator should also be inspected for proper operation and alignment with the valve stem. If any issues are detected, the valve should be disassembled and inspected for internal damage or wear.
