Why is the VTS520 series the \"best choice\" for solar DHW?\u003c\/h4\u003e\n\u003cp\u003eThe VTS520 is built with materials and a thermostatic cartridge designed to withstand the \u003cb\u003esignificantly higher temperatures\u003c\/b\u003e that can be reached in a DHW tank heated by solar collectors, unlike standard thermostatic valves that may fail or wear out prematurely under these conditions.\u003c\/p\u003e\n\u003ch4\u003e2. How does the VTS520 differ from the VTA320 Series?\u003c\/h4\u003e\n\u003cp\u003eWhile the VTA320 is a universal valve for standard applications and underfloor heating, the \u003cb\u003eVTS520 is specific to solar systems\u003c\/b\u003e with high temperatures. Additionally, the VTS520 offers larger diameter connections (up to 1 1\/4\" and high flow) and a higher regulation range (up to 65°C) than the VTA320 (up to 60°C).\u003c\/p\u003e\n\u003ch4\u003e3. Does the adapter kit include check valves?\u003c\/h4\u003e\n\u003cp\u003eYes. The VTS520 product range supplied with connection kits includes three adapter connectors along with \u003cb\u003etwo check valves\u003c\/b\u003e.
