Electro-pneumatic pressure regulator

22 January 2008

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 factory automation applications.

High dynamics with small dimensions is now possible with Rexroth’s ED02 pressure regulators. Featuring compact dimensions of only 76mm x 60mm x 30mm, the new pressure regulator is applicable to almost all sectors, including the automotive, printing and paper technology, and food industries. Thanks to a construction with two directly-controlled 2/2-way proportional valves, a dynamic is attained with an air flow of 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, Rexroth’s 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 from Rexroth 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, analogue 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 300mA maximum: from simple remote pressure adjustment to complex control. Additionally, Rexroth’s ED02 is available with sealing to IP65, compatible with the harsher environments where they are generally installed.

Rexroth’s ED02 joins the ranks of a series of electro-pneumatic pressure regulators, including the ED05 with 1000 l/min flow, the ED07 with up to 1300 l/min and the ED12 with flows of 2600 l/min, making it easier to find the right valve for every application.
