## Summary description

Three-way mixing valve DN20 (3/4") with Kvs 6.3 from IMI TA, model R051503020. Designed to blend or divert hot and cold water flows in heating and cooling systems. Compact DN20 body suitable for residential and light-commercial hydronic circuits, provides a Kvs flow coefficient of 6.3 for predictable flow control. Commonly used for temperature control, mixing loop regulation and system balancing.

## Long description

The Three-way mixing valve DN20 (3/4) Kvs 6.3 IMI TA R051503020 is a compact hydronic valve designed to blend or divert water flows in heating and cooling circuits. With a DN20 (3/4") body and a Kvs flow coefficient of 6.3, the valve provides predictable flow characteristics for residential and light-commercial applications. The valve is intended for use in mixing loops, temperature control assemblies and system balancing where reliable modulation of supply and return flows is required.
Advantages
This three-way mixing valve offers a compact design that integrates easily into existing DN20 pipework and hydronic manifolds. The specified Kvs 6.3 ensures stable flow performance and repeatable mixing behaviour across typical operating differentials. Built to IMI TA standards, the valve supports accurate temperature regulation and reduces hydraulic interference between supply circuits when used in mixing or diverting configurations.
Suitable for
Domestic and light-commercial heating systems
Cooling circuits in small commercial installations
Mixing loops for underfloor heating or radiator circuits
Temperature control and setpoint maintenance
Hydronic system balancing and flow diversion
Key specifications
Nominal diameter: DN20 (3/4")
Kvs (flow coefficient): 6.3
Function: three-way mixing/diverting valve
Suitable media: water and water/glycol mixtures compatible with standard hydronic systems
Applications: mixing loops, temperature control, flow diversion, system balancing
How to use
Install the valve in the piping layout according to the intended function—mixing or diverting—observing correct flow direction indicated by the valve body. Connect to DN20 pipework using compatible fittings and ensure secure sealing. Integrate an actuator or control device compatible with the valve to enable modulating operation for temperature control. Commission the system by verifying flow paths, adjusting control settings to achieve the desired temperature or flow split, and checking for leaks under operating pressure.
Usage recommendations
Use the valve with fluids and additives that are compatible with standard hydronic components; avoid aggressive chemicals. Where glycol is used, confirm concentration limits with system documentation. Regularly inspect joints and actuators and perform routine system flushing and filtration to prevent debris from impairing valve performance.
