Compact Directional Valves - Stand-alone 4-way directional valves - Size 10 - 90 l/min

LC2F-DZ

4 way, 2 or 3 position spool type solenoid operated directional valves.

Stand-alone valve body intended for “in-line” application. Available with a choice of threaded ports; mounting surface with installation holes for direct fitting on the machine structure.

Zinc plated body with yellow trivalent chrome treatment. 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).

Plug-in connectors available: EN 175301-803 (was DIN 43650); AMP Junior; DT04-2P (Deutsch), free leads. Coils removable.

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

Spool variants (for different hydraulic schemes) are available for both 2 and 3 position versions.

Size 10

Series 00

Maximum operating pressure 250 bar (3600 psi)

Maximum flow 90 l/min (23.8 gpm)

Port connections G 1/2 – SAE10

The directional valves LC2F_DZ are compact direct operated solenoid valves which control the start, the stop, the direction of the oil flow. They basically consist of a housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4). When energized, each solenoid (5) displaces the control spool (2) from its neutral-central position to the “a” or “b” position and the oil flow P is diverted to A, or to B. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer back against the housing and the spool (2) returns in its neutral-central position “0”. Each coil is fastened to the solenoid tube (5) 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.
