## Summary description

Herz CALIS-TS-RD is a three-way brass mixing valve with nominal diameter DN32, G 1½ (internal thread), and a Kvs flow coefficient of 6.44. Designed for hydraulic systems to mix or divert heating and cooling media, it suits applications in heating circuits, domestic hot water systems, and HVAC installations where controlled proportioning of flow and temperature is required.

## Long description

Herz CALIS-TS-RD DN32 G 1½ is a three-way brass mixing valve designed for hydraulic systems where controlled mixing or diverting of heating and cooling media is required. With a nominal diameter of DN32 and an internal G 1½ connection, the valve provides a Kvs flow coefficient of 6.44 for predictable flow characteristics. It is suitable for installation in heating circuits, domestic hot water systems and HVAC applications that require reliable proportioning of flow and temperature.
Advantages
The brass construction offers corrosion resistance and mechanical durability while maintaining dimensional stability under typical system temperatures. The DN32 size and G 1½ internal thread provide compatibility with standard piping found in residential and commercial installations. A Kvs value of 6.44 ensures defined flow behaviour for hydraulic balancing and temperature control tasks. The compact three-way design enables both mixing and diverting functions without the need for multiple separate valves.
Suitable for
 Mixing of supply and return lines in heating circuits
 Proportioning hot water for domestic hot water systems
 Diverting flow in HVAC distribution and terminal units
 Integration into pump stations and manifold assemblies
Key specifications
 Valve type: Three-way mixing/diverting valve
 Material: Brass body
 Nominal diameter: DN32
 Connection: Internal thread G 1½
 Kvs (flow coefficient): 6.44
 Function: Mixing and diverting of heating/cooling media
How to use
Install the valve inline according to the hydraulic scheme, observing flow direction and port assignments for mixing or diverting operation. Ensure sealing of threaded connections with appropriate thread sealant compatible with system media. Commission the valve by adjusting the actuator or manual control to achieve the required temperature or flow proportioning, and verify system pressures and temperatures during initial operation. Regular inspection of joints and function is recommended as part of routine system maintenance.
Usage recommendations
Use in systems that operate within the valve’s material and temperature limits, and pair the valve with compatible actuators or controls for precise temperature regulation. Follow local codes for installation and pressure testing, and use appropriate sealing materials to prevent leaks.
