## Summary description

4-way mixing valve IMI TA R051504020 for hydronic systems, nominal diameter DN20 with 3/4" connections and flow coefficient Kvs 6.3. Designed to blend and divert heating or cooling circuits, it suits temperature control, system balancing and zone regulation in commercial and residential installations. Compatible with actuators and standard piping.

## Long description

The 4-way mixing valve IMI TA R051504020 DN20 3/4" Kvs 6.3 (DWZ) is a compact hydraulic control valve for hydronic heating and cooling systems. With a nominal diameter DN20 and 3/4" connections, it is engineered to blend or divert fluid streams to achieve required supply temperatures, enable bypass control and support zone regulation. The valve's Kvs 6.3 flow coefficient provides predictable flow behavior for balancing and commissioning tasks, and the unit is compatible with standard electric or pneumatic actuators and conventional piping installations.
Advantages
The valve offers precise mixture control and repeatable hydraulic performance to maintain stable system temperatures. Its DN20 size and 3/4" connections make it suitable for a wide range of small-to-medium circuits while keeping installation footprint minimal. Compatibility with common actuators simplifies integration into existing control schemes, and the valve design supports both blending and diverting functions, reducing the need for separate components in multi-zone systems.
Suitable for
Temperature control in domestic and commercial heating systems
Mixing supply and return circuits to achieve setpoint temperatures
Bypass or diverting applications in hydronic cooling loops
Zone regulation and system balancing in multi-zone installations
Key specifications
Valve type: 4-way mixing/diverting valve
Nominal diameter: DN20
Connection size: 3/4" threaded connections
Flow coefficient (Kvs): 6.3
Function: blending and diverting of heating/cooling circuits
Compatibility: designed for use with standard electric or pneumatic actuators
Application: hydronic heating and cooling systems
How to use
Install the valve into the piping layout according to the system design ensuring correct orientation for mixing or diverting operation. Connect compatible actuator and control wiring following actuator manufacturer instructions and the system control strategy. Commission the valve by adjusting control signals and verifying temperatures and flows at each port to achieve the desired setpoints. Routine inspection of seals and connections is recommended to maintain leak-free operation.
Usage recommendations
Use water-treated or otherwise appropriate heat-transfer fluids, and follow local codes for pressure and temperature limits. When replacing or retrofitting, confirm actuator compatibility and allow for sufficient straight pipe lengths upstream and downstream for stable flow characteristics. Schedule periodic checks during initial commissioning and at regular maintenance intervals to verify calibration and detect wear.
