EC082B
The document outlines the specifications for the SAE8 2-way/2-position electric valves, model EC082B. These valves are pilot-operated and available in normally closed (CNN), normally open (ONN), and normally closed with emergency (CNV) configurations. The maximum flow rate is 40 l/min (10.8 USgpm), and the maximum pressure is 350 bar (5075 PSI). The approximate weight is 0.16 kg (0.35 lbs), and the tightening torque is 30 Nm (22 lbt ft). The cavity type is SAE 8/2.
The valves are designed to operate with mineral oil ISO 6743/4 (DIN 51524) with a viscosity range of 15-250 mm2/s (15 to 250 cSt). The maximum contamination class is ISO 4406:1999 Class 18/16/13. The oil temperature range is -20°C to +80°C (-4°F to +176°F), and the environment temperature range is -20°C to +50°C (-4°F to +122°F). A filter with 15 μm filtration is recommended to protect the valve. The maximum leakage is 0.25 cm3/min (5 drops/min).
Performance tests were conducted with solenoids at their working temperature, with a supply voltage 10% below the nominal value. The document includes performance graphs showing flow rates and pressure relationships.
The ordering code for the valves is provided, and additional information about the 22 W coil and connector can be found on pages 102-103 of the catalog.
