The valve is selected for the required set pressure. As the pressure rises, when the discharge pressure is reached the valve opens and discharges to atmosphere, preventing the pressure within the system reaching levels which might damage the solar collectors and other equipment installed in the system.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e 1\/2\" x 3\/4\"\u003cbr\u003e \u003cstrong\u003eConnections:\u003c\/strong\u003e BSP Female Inlet x BSP Female Outlet\u003cbr\u003e \u003cstrong\u003eMaterials:\u003c\/strong\u003e Brass (Chrome Plated)\u003cbr\u003e \u003cstrong\u003eMedium:\u003c\/strong\u003e Water, Glycol Solutions (Max.
