❓ Frequently Asked Questions (FAQ)
1. Why is the VTS520 series the "best choice" for solar DHW?
The VTS520 is built with materials and a thermostatic cartridge designed to withstand significantly higher temperatures that can be achieved in a domestic hot water tank heated by solar collectors, unlike standard thermostatic valves which can fail or wear out prematurely under these conditions.
2. How does the VTS520 differ from the VTA320 Series?
While the VTA320 is a universal valve for standard and underfloor heating applications, the VTS520 is specifically designed for solar systems with high temperatures. In addition, the VTS520 offers larger diameter connections (up to 1 1/4").4" and high flow rate) and a higher regulation range (up to 65°C) than the VTA320 (up to 60°C).
3. Does the adapter kit include check valves?
Yes. The VTS520 product range supplied with connection kits includes three adapter connectors along with two check valvesThis greatly simplifies installation and ensures the necessary unidirectional flow in the system.
