Why You Need a Pressure Relief Valve
In closed-loop solar water heating and hydronic heating systems, pressure and trapped air can build up over time. Without proper venting, this leads to reduced efficiency, noisy pipes, and potential system damage. This automatic exhaust valve releases air pockets while the integrated pressure relief function ensures your system never exceeds safe operating limits — giving you peace of mind and prolonging the life of your equipment.
Made in Mainland China.
