pressure valve 99229018 DDA 30-4 FCM-PVC/V/C-F-32I002F 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).
