pressure valve 99229033 DDA 17-7 AR-PV/E/C-F-32U2U2FG The SMARTPressure valves provide a constant counterpressure and prevent siphoning Opening pressure is fix at 3 bar. They are particularly required for DDA FC or DDA FCM pumps at very small flow rates. Pressure valves are installed either directly on the pump discharge side, or on the pressure relief valve. Spring material is Alloy C 4 (NiMo16CrTi, material number 2. 4610).
