Compact Electro-Pneumatic Pressure Regulator

Oct. 6, 2006
The new electro-pneumatic ED02 pressure regulator from Rexroth offers high accuracy and dynamics. Combined with its compact design, it performs well in a very wide range of applications. High dynamics with small dimensions: this is possible with ED02 pressure regulators with compact dimensions of only 3” x 2.4” x 1.2” (76x60x30 mm). Thanks to a construction with two directly-controlled 2/2-way proportional valves, a dynamic is attained with an air flow of 3.5 SCFM (100 l/min) that is only possible with larger nominal widths in other units. Exact regulation controlled by a microprocessor is an additional feature of the new pressure regulator. Here, the ED02 provides repetitive precision of 0.44 psi (30 mbar) and excellent values with a hysteresis of 0.73 psi (50 mbar). Four ED02 series pressure regulators can be linked to each other without a base plate. Compressed air supply is possible from both sides, permitting extremely flexible use in a system. The supply voltage, analog set point and actual value are electrically connected via a central M12 plug. The unit is universally applicable in spite of a low power consumption of 300 mA maximum: from simple remote pressure adjustment to complex control. Additionally, the ED02 is available with the IP65 (NEMA 4) protection class, i.e. dust-tight and jet-proof. The new pressure regulator is thus a good addition to almost all sectors, such as the automotive industry, printing and paper technology industry, and food industry.
