1 The Oventrop Quality Management System is certified to DIN-EN-ISO 900 Technical information Thermostatic radiator valves Function: Oventrop thermostatic radiator valves are proportional regulators working without auxiliary energy. They regulate the room temperature by varying the flow volume of heating water. Technical data: Nominal flow: (see charts) Max. flow of heating water: (see charts) Max. differential pressure against which the radiator valve closes: 4.5 psi: Series A, AV 6, ADV 6, RF, RFV 6, RFZ, AZ, P 4.5 psi Series F Valve body material: bronze, brass, nickel plated Differential pressure effect:0.
