Three-way valves with servo

Three-way valves with servo drives are used in heating and cooling systems to control the flow of hot and cold water. These valves can function as switching or mixing valves and are suitable for household and small industrial applications. The valves allow flow interruption between different paths independently of pressure, making them ideal for zoning and temperature regulation in hydronic systems.

The valves are constructed from nickel-plated brass (CW617N) and feature a removable valve head for maintenance and replacement. They operate at a supply voltage of 230 V and consume 4 VA of power. The operating temperature range is from -40°C to +100°C, and the valves are rated for a pressure class of PN 40.

How to choose

• Select the appropriate connection size (e.g., 3/4", 1", 5/4", 6/4") based on the system's pipe dimensions and flow requirements.
• Ensure compatibility with the system by checking the thread type (MM for MODULO COMPACT 3, MMM for MODULO PLUS 3).
• Consider the torque requirements: 8 Nm for MODULO COMPACT 3 and 28 Nm for MODULO PLUS 3, depending on the application's mechanical demands.
• Verify the IP rating (IP50 or IP55) based on the installation environment to ensure adequate protection against dust and water.
• Confirm the rotation angle (180°) and time constant (120 s) to match the system's response and control needs.

Frequently asked questions

Can these valves be used in both heating and cooling systems?
Yes, they are suitable for both heating and cooling applications where switching or mixing of hot and cold water is required.

What is the maximum operating temperature of these valves?
The valves can operate in environments with temperatures ranging from -40°C to +100°C.

Are the valve heads removable?
Yes, the valve head is designed to be removable, facilitating maintenance and replacement without disassembling the entire unit.
