VTNx00 – SIMPLE, CHEAP, AND AN INGENIOUS PROTECTION!

ESBE’s design with axial seal

The VTN series is designed with an axial seal solution that prevents the seal from getting stuck due to inactivity. The solution uses the flowing water in the valve to exercise the seal, making sure it’s never standing still in a fixed position. Thanks to this, the valve can open and close repeatedly without issues.
 

High media temperature range
EBSE VTN has one of the widest media temperature ranges on the market: 0–90 °C! This means that our valve can be used in systems with heat pumps that use propane (R290) as a refrigerant, where the water temperature can reach up to 75-80°C compared to approximately 65°C achieved in traditional systems. This type of heat pump will become increasingly common as they are more future-proof in relation to EU regulations.
 

 Can be used for both heating and cooling
The VTN200 works great for heat pumps that control both heating and cooling, thanks to the ambient temperature sensor that overrides the drain function as long as the ambient temperature doesn't drop below 5°C. This ensures that the system doesn’t drain accidentally during hot summer days when the system is running for cooling.

Automatic reset

The valve opens when the water temperature drops below 3°C and begins to drain the system in a controlled manner. When the water temperature returns above 4°C, the valve closes automatically and the function is restored. All you need to do is refill the system with water.

No electricity needed 

The valve uses a wax element to measure the water temperature and to control the valve. Wax elements are a well-proven and safe method that uses the temperature change in the water and converts it into physical movement. In VTN’s case, to open and close the valve without electricity.
