Apollo® Valves 78-300 Series 78317RV Thermal Expansion Relief Valve, 3/4 in Nominal, C Connection, 100 psig Pressure 78317RV

The Apollo® EXV thermal expansion relief valves are designed primarily to relieve excessive water pressure build-up caused by thermal expansion. In a closed hot water piping system, as water is heated, thermal expansion occurs. The increase of pressure will exert unwarranted stress on the system components, which may reach harmful levels well before the emergency setting of the main relief valve is reached. By installing the Series EXV, it will control any amount of expanded water without causing pressure increase to exceed maximum setting.
