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 General Pump safety blocks type DBAW are pilot-operated pressure relief valves which are integrated into a block and intended to be mounted directly onto SAE pressure ports of pumps. They are used for limiting and solenoid-actuated unloading (type DBAW) the operating pressure. Pump safety block type DBAW In principle, the function of this block corresponds to the function of block type DBA.... Unloading the main control spool, however, is achieved by controlling the mounted directional valve (15). In this case, no cover plate (4) is required. Pump safety block type DBAW.B…Z… for displacement pumps (with pressure relief valve) In principle, the function corresponds to type DBAW.... By means of the pressure relief valve type ZDB 6 (16) (data sheet 25751) and actuation of the directional valve (15), the pilot control of the pressure limitation screw-in cartridge valve type DB 20 K is deactivated and the pressure set at the pressure relief valve type ZDB 6 is activated. The pressure adjustment at the pressure relief valve type ZDB 6 only works if it is below the setting of the pressure limitation screw-in cartridge valve type DB 20 K. Pump safety block type DBAW.B…Z…A for control pump A10V... (with pressure relief valve) In principle, the function corresponds to type DBAW.... By means of the pressure relief valve type ZDB 6 (16) (data sheet 25751) and by actuation of the directional valve (15), a pressure change is achieved at control port X. The pressure change set at the pressure relief valve type ZDB 6 acts on the controller of the pump. The pressure adjustment at the pressure relief valve type ZDB 6 only works if it is below the setting of the pressure limitation screw-in cartridge valve type DB 20 K. Pump safety block DBAW.B…ZZ…A for control pump A10V... (with pressure relief valve) In principle, the function corresponds to type DBAW.... By means of the pressure relief valve type Z(2)DB 6 (16) (data sheet 25751) and by actuation of the directional valve (15), two pressure adjustments are possible at control port X. The pressure adjustment at the pressure relief valve type Z(2)DB 6 only works if it is below the setting of the pressure limitation screw-in cartridge valve type DB 20 K. 1) Illustration rotated by 90° 2) Port X is illustrated with an offset of 90° Type code 01 02 03 04 05 06 07 08 09 10 11 12
