Two-way valves with servo

This category includes two-way zone valves with integrated servo drives, designed for use in residential and small-scale heating, cooling, and water systems. These valves are used to regulate or isolate the flow of hot and cold water in applications such as underfloor heating, room zoning, and temperature control systems. The valves are available in various connection sizes and are suitable for both switching and mixing functions.

The valves are constructed with nickel-plated brass (CW617N) and feature a removable valve head for maintenance and servicing. They operate at a supply voltage of 230 V and have a power consumption of 4 VA. The operating temperature range is from -40 °C to +100 °C, and the pressure rating is PN 40. The rotation angle is fixed at 90°, with a time constant of 60 seconds.

How to choose

• Select the appropriate connection size (e.g., 1/2", 3/4", 1", 2", etc.) based on the pipe dimensions and flow requirements of the system.
• Ensure compatibility with the control system by verifying the supply voltage and input power requirements.
• Consider the torque rating (8 Nm for MODULO COMPACT 2, 28 Nm for MODULO PLUS 2) to match the system's hydraulic resistance and actuation needs.

Frequently asked questions

Can these valves be used in both heating and cooling applications?
Yes, the valves are suitable for both heating and cooling systems due to their wide operating temperature range and pressure rating.

What is the maximum torque available in this range?
The MODULO PLUS 2 model provides a maximum torque of 28 Nm, making it suitable for systems with higher hydraulic resistance.
