4WE6H73A6X/EG24N9K4/A12 Rexroth directional short tube valve
Function and components:
The WE model directional valve is a directional spool valve driven by an electromagnetic coil and can be used as an electromagnetic component. These valves control the start, stop, and direction of the fluid. Is the basic structure of this directional valve a housing? (1) One or two electronic coils? (2) Control valve core? (3) And the reset spring? (4) . Control valve core in case of power outage? (3) By resetting the spring? (4) Fixed in the center position or initial position (excluding model 'O'). When wet plug electronic coils? (2) When powered on, control the valve core? (3) Move from a stationary position to the desired terminal position. This way, the required flow direction can be released according to the selected valve core function. Turning off the electronic coil? (2) After that, control the valve core? (3) Will be pushed back to the center position or initial position (except for valves with 'OF' locators and valves without springs). Manual emergency operation? (5) Allow manual valve switching when the coil is not energized.
To ensure the undisputed operation of the equipment, the hydraulic system must be properly drained. Without spring reset 'O' (only applicable for valve core functions A, C, and D), this model of directional valve has two valve core positions and two electronic coils, without a positioner. Control valve core? (3) Valves without spring reset do not have a determined initial position in the event of a power outage.
This model of directional valve has two valve core positions and two electronic coils, and includes a locator. It does not come with a spring reset and comes with an 'OF' locator (only available for valve core functions A, C, and D). Are brakes used to control valve cores? (3) Fixed at the relevant valve core position. Therefore, during the operation, there is no need to continuously apply current to the electronic coil, which helps with energy-saving operations.
Models'. 73... A12 '(smooth switching behavior) significantly reduce the directional shock that occurs when activating and closing the valve by controlling the structural design of the valve core and coil. Compared to standard valves, the design of the control valve core can reduce directional shock (measured as acceleration value a) by approximately 85% (for more information, please refer to 'Acceleration Value' on page 13).
Notes:
If the model is equipped with a locator, the pressure peak of two or more valves in the fuel tank pipeline may cause unexpected control valve core movement. Therefore, we suggest providing a separate return oil pipeline or installing a one-way valve in the fuel tank pipeline. Due to design principles, internal leakage is inevitable in valves, and the amount of leakage will increase with the extension of service life.
