Description Size 16 … 32 Component series 2X Maximum operating pressure 350 bar Maximum flow 400 l/min Features Zero-pressure start-up and circulation of the pump Intended for direct mounting onto the SAE pressure port of the pump Low circulation pressure due to short distance Low compression volume for soft switching to depressurized circulation Quick pressure build-up Low noise level due to direct flange mounting at the pump CE conformity according to the Low-Voltage Directive 2014/35/EU for electrical voltages >50 VAC or >75VDC Solenoid coil as approved component with UR marking according to UL 906, edition 1982, optional Product description Pump safety block type DBAEA for variable displacement pumps type A10V.. (with proportional pressure relief valve) In principle, the function corresponds to type DBA.... By means of the proportional pressure relief valve type DBETA-6X… (17), a pressure change is achieved at the control port X. The pressure change acts on the controller of the pump. The cover plate (4) is not required. The pressure adjustment at the proportional pressure relief valve type DBETA only works if it is below the setting of the pressure limitation screw-in cartridge valve type DB 20 K. The pump control is pressure-controlled. This way, linear and stable behavior as well as increased accuracy of pump adjustment can be achieved. 1) Illustration rotated by 90° Type code 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 DBA EA 2X / G24 K4 01 Pump safety block DBA 02 With mounted proportional pressure relief valve (pressure-controlled) with integrated control electronics, DBETA-6X/… EA 03 Size 16 15 Size 25 25 Size 32 30 04 Without directional valve no code With mounted directional valve, normally closed A With mounted directional valve, normally open B Type of connection / SAE flange 1) 05 Standard flange (250 … 350 bar) F High-pressure flange (350 bar) H Adjustment type for pressure adjustment 2) 06 Rotary knob 1 Sleeve with hexagon and protective cap 2 Lockable rotary knob with scale 3 3) Rotary knob with scale 7 07 Without pressure switch – With mounted pressure switch type HED 8 OH… (connector according to DIN EN 175301-803, without mating connector), (data sheet 50061) D 4) 08 Component series 20 … 29 (20 … 29: unchanged installation and connection dimensions) 2X Pressure rating 6) 09 Set pressure up to 50 bar 50 Set pressure up to 100 bar 100 Set pressure up to 200 bar 200 Set pressure up to 250 bar (only NG32 and standard flange "F") 250 Set pressure up to 315 bar 315 Set pressure up to 350 bar 350 10 Without additional pressure relief valve no code 11 Standard version no code 12 Without directional valve no code 13 Direct voltage 24 V G24 14 Without manual override no code Electrical connection 15 Without mating connector; connector DIN EN 175301-803 K4 4) Interface electronics 16 Command value 0 … 10 V A1 Command value 4 … 20 mA F1 Nozzle fitting 17 Fixed pumps Lateral channel closed, transverse channel open, pilo
