Operating Principle and Structure<\/h3>\n

The AMI DB3C-DB3 Directional Control Valve represents a high-precision hydraulic solution based on sectional valves for directional control. The series is available in ON\/OFF configurations, sectional proportional valves, and flow-compensated proportional valves. Engineered with solid cast iron sections, these directional control valves ensure high resistance to mechanical stress and feature an anti-rust surface treatment for operation in harsh industrial environments. The valve body is pre-arranged for standard threaded ports or modular valve interfaces, providing broad installation flexibility in both compact systems and complex high-flow architectures.<\/p>\n

Hydraulic Performance and Pressure Specifications<\/h3>\n

The directional control valve family is divided into two primary frame sizes: the DB3C series, optimized for reduced dimensions with a nominal flow rate of 30 l\/min (8 gpm), and the DB3 series, designed for higher flow rates up to 50 l\/min (13 gpm). Both models support a maximum working pressure of 310 bar (4500 psi) and tolerate a maximum return line backpressure of 210 bar (3048 psi). The system guarantees excellent sealing, with a maximum internal leakage (A\/B -> T at \u0394p=100 bar) limited to just 13 cm\u00b3\/min. Integrated standard relief valves feature variable setting ranges depending on the model: from 20 to 250 bar for the DB3C and from 50 to 310 bar for the DB3.<\/p>\n

Circuit Adaptability and Fluid Management<\/h3>\n

The directional control valves are configurable to operate in both parallel and series circuits, along with pre-arrangement for Load Sensing systems. Fluid control is optimized for mineral oils (reference test with ISO-VG32) having a kinematic viscosity between 12 and 400 mm\u00b2\/s. Standard NBR seals allow a fluid operating temperature range from -30\u00b0C to +80\u00b0C, while mechanical and electrical components can operate in ambient temperatures between -20\u00b0C and +50\u00b0C.<\/p>\n

Electrical Modules and Control Configurations<\/h3>\n

Directional control is managed via electrical actuation using high-performance coils. Solenoids are available in direct current (12V, 24V, 48V DC) and alternating current (110V + RAC) variants. Power consumption varies based on circuit configuration: 26 Watts (2.15A at 12V) for parallel or series circuits with an unloader valve, and 60 Watts (5A at 12V) for series circuits without an unloader valve. Control options include double-solenoid configurations with spring return, single solenoid on side A, and single solenoid on side B, covering a wide range of flow paths and spool overlaps.<\/p>\n

Product codes<\/h3>\n

The AMI DB3C-DB3 Directional Control Valve family features high modularity. Rather than static individual product codes, the series is ordered by assembling a modular ordering code string that identifies each specific attribute, allowing thousands of configurations to be generated. The configuration breakdown for the orderable code family is outlined below.<\/p>\n
