## Summary description

Honeywell 3-way mixing valve V5433A1049, DN25 with KVS10 flow coefficient. Designed for mixing and diverting hot water in heating and HVAC systems, it provides stable flow control and temperature regulation when combined with actuators and controllers. Suitable for residential and commercial installations where accurate mixing and reliable operation are required.

## Long description

Honeywell 3-way mixing valve V5433A1049 DN25 KVS10 is a compact valve designed for controlled mixing and diverting of hot water in heating and HVAC systems. The valve body and internal geometry are optimized for stable flow distribution and reliable modulation when paired with compatible actuators and controllers. Its DN25 size and KVS10 flow characteristic make it suitable for medium-duty residential and light commercial installations where predictable temperature regulation and hydraulic balancing are required.
Advantages
The three-way design supports both mixing and diverting functions in a single compact unit, reducing piping complexity. The valve delivers consistent flow behaviour thanks to its calibrated KVS value, which facilitates accurate temperature control when used with control actuators. Constructed for durability in heating system environments, the valve is compatible with common actuator interfaces and mounting standards, enabling straightforward integration into existing HVAC assemblies.
Suitable for
 Domestic central heating systems requiring temperature mixing
 Small commercial HVAC installations for hydraulic control and zoning
 Systems that need a compact solution for diverting or blending hot water
 Applications where actuator-driven proportional control is used
Key specifications
 Valve type: 3-way mixing/diverting valve
 Nominal size: DN25
 Flow coefficient: KVS 10
 Function: mixing or diverting hot water in heating circuits
 Suitable media: hot water for heating systems
 Typical mounting: inline with actuator interface for motorized control
How to use
Install the valve in accordance with system design, observing flow direction and flange/connection orientation for DN25 piping. Connect a compatible actuator to the valve’s actuator mounting interface and configure the control signals via the system controller to achieve the required mixing or diverting behaviour. Commission the assembly by verifying stroke range and calibrating control parameters to obtain the desired temperature setpoint and stable hydraulic balance. Follow local codes and manufacturer guidance for pressure testing and filling the system.
Usage recommendations
Use corrosion-resistant pipe fittings and appropriate sealing materials for hot water systems, and ensure the actuator and controller are rated for the valve’s operational duty. Schedule periodic checks for leakage, actuator performance, and hydraulic balance to maintain consistent temperature control and prolong component life.
