Four-way sets

Four-way sets are pre-assembled kits that combine a four-way mixing valve with an electric actuator. These kits are designed for use in heating systems where precise temperature control is required, such as in underfloor heating, domestic hot water circuits, and radiant panel systems. The sets are suitable for systems operating at a maximum temperature of +120°C and pressure rating PN10.

How to choose

• Select the appropriate nominal size (1", 3/4", 2", 5/4", or 6/4") based on the flow rate and pipe dimensions of the system.
• Ensure the actuator torque (5 Nm or 10 Nm) matches the system’s hydraulic resistance and valve size.
• Verify compatibility with the control system, as all actuators operate on 230 V, 50/60 Hz and have an IP41 protection rating.
• Confirm the valve material (CW617N brass) is suitable for the system’s chemical and thermal conditions.
• Choose between the MIX 4 and MIX 4 BIG variants depending on the required flow capacity and system scale.

Frequently asked questions

Can the actuator be replaced separately?
Yes, the actuator is a separate component and can be replaced if needed, provided the new unit matches the voltage and torque specifications.

What is the maximum operating temperature for these sets?
The sets are rated for a maximum temperature of +120°C, suitable for most heating and hot water applications.
