Compact Directional Valves - Non-compensated and Post-compensated - Directional elements ED Series

ED1-Z

Valve elements with solenoid operated directional spool. Control spools operated by solenoids with removable coils.

In the de-energized condition, the control spool is held in the central position by return springs.

Wet pin tubes for DC coils, with push rod for mechanical override; nickel plated surface.

Coils can be rotated 360° around the tube; they can be energized by AC current through special connectors with rectifier (RAC).

Manual override (push-button or screw type) available as option.

Size 6

Series 00

Maximum operating pressure 310 bar (4500 psi)

Maximum flow 30 l/min (7.9 gpm)

Port connections G 3/8 - SAE6

NEW spool position sensor available for this valve. See RE18300-30

The sandwich plate design directional valve elements L8_10… are compact direct operated solenoid valves which control the start, the stop and the direction of the oil flow. These elements basically consist of a stackable housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4).

When energized, the force of the solenoid (5) pushes the control spool (2) from its neutral-central position “0” to the required end position “a” or “b”, and the required flow from P to A (with B to T), or P to B (with A to T) is achieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool returns in its neutral-central position.

Each coil is fastened to the solenoid tube by a ring nut (6). A pin (7) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.
