## Long description

Four-way mixing valve INVENA CM-04-025 is a plumbing mixer valve designed to blend and direct flows in heating and hot-water systems. As a four-port mixing device, it manages the distribution between supply and return lines to achieve desired fluid temperature and stable flow. The valve is intended for integration into boiler circuits, underfloor heating manifolds and other residential or commercial heating installations where accurate mixing and flow control are required.
Advantages
The four-way configuration enables simultaneous control of supply and return streams, reducing temperature fluctuations and improving system stability. The valve's design supports consistent mixing performance across typical domestic and light commercial heating applications. It simplifies piping arrangements by providing a single component to handle mixing tasks that would otherwise require multiple fittings or more complex assemblies.
Suitable for
 Boiler circuits requiring mixed return and supply control
 Underfloor heating manifolds and zone mixing
 Domestic and small commercial heating systems
 Hydronic circuits where temperature blending is necessary
Key specifications
 Type: four-way mixing valve for plumbing and heating systems
 Function: mix and direct fluid between supply and return lines
 Application: use in boiler circuits, underfloor heating manifolds and hydronic installations
 Compatibility: suitable for hot-water and heating system fluids within normal operating temperature ranges
 Installation: inline mounting in piping networks designed for heating distribution
How to use
Install the four-way mixing valve in the piping layout according to the system schematic, ensuring correct orientation of supply, return, mixed and bypass ports. Connect to compatible pipe sizes and fittings, use appropriate sealing materials and torque values for threaded or flanged connections. After installation, adjust the valve settings or actuator according to the required mixing ratio or temperature setpoint and commission the system by flushing and checking for leaks. Verify proper operation under typical load conditions and make fine adjustments as needed to maintain stable supply temperatures.
Usage recommendations
Ensure the valve is installed by a qualified plumber or heating engineer, and follow local codes and manufacturer installation practices. Regular inspection and maintenance, such as checking seals and actuators, will help preserve mixing accuracy and prolong service life. Use compatible fluids and avoid abrasive or chemically aggressive media.
