Two potential-free output relays for maximum 30 V AC/DC (configurable

DDA 12-10 AR-PP/V/C-F-31U2U2FG The SMART Digital DDA is a compact positive displacement

DDA 30-4 FCM-PVC/V/C-F-32I002F The SMART Digital DDA is a compact positive displacement

50 % and 25 % maximum flow

The motor is controlled by a frequency converter and protected by Pt100 sensors

pressure valve 99229018 Two potential-free output relays forPressure 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).
