❓ Frequently Asked Questions (FAQ)

1. What is the advantage of a 4-way mixing valve over a 3-way mixing valve?

A 3-way valve mixes or diverts the flow. 4-way valve (VRG140) It can mix and simultaneously split the flow into two different circuits or keep one main circuit closed while mixing another. This is crucial for efficient energy management in systems that combine different sources of heat or cooling (e.g., heating and solar power).

2. What is the wide temperature range (-10° to 130°C) used for?

This wide operating range ensures that the VRG140 valve can be used reliably in applications of refrigeration (low temperatures) as in circuits of solar heating or high-efficiency boiler (high temperatures), without compromising the integrity of the seals or the valve body.

3. What other actuators are compatible with the VRG140 besides the ARA600 Series?

In addition to the ARA600 Series, ESBE's more advanced temperature controllers, such as the CRB or CRC Series, are compatible. These controllers utilize the unique interface of the VRG140 valve to provide more sophisticated control functions (e.g., based on outdoor temperature or schedules).
