The valve type H-4WEH is a directional spool valve with electro-hydraulic actuation. It controls the start, stop and direction of a flow.
The directional valve basically consists of the main valve with housing (1), the main control spool (2), one or two return springs (3.1) and (3.2), as well as the pilot control valve (4) with one or two solenoids "a" (5.1) and/or "b" (5.2).
The main control spool (2) in the main valve is held in the zero or initial position by the springs or by means of pressurization. In the initial position, the two spring chambers (6) and (8) are connected with the tank in a depressurized form via the pilot control valve (4). Via the control line (7), the pilot control valve is supplied with pilot oil. Supply can be implemented internally or externally (externally via port X).
Upon actuation of the pilot control valve, e. g. solenoid "a", the pilot control spool (10) is moved to the left and thus, the spring chamber (8) is pressurized with pilot pressure. The spring chamber (6) remains depressurized.
The pilot pressure acts on the left side of the main control spool (2) and moves it against the spring (3.1). This connects ports P with B and A with T in the main valve. On switching off of solenoid, the pilot control spool (10) returns to its initial position (except impulse spool). The spring chamber (8) is unloaded to the tank.
The pilot oil return is implemented internally (via channel T) or externally (via channel Y).
An optional manual override (9) allows for moving of the pilot control spool (10) without solenoid energization.
The return springs (3.1) and (3.2) in the spring chambers (6) and (8) hold the main control spool (2) in central position without pilot pressure even with, for example, vertical valve positioning.
Due to the design principle, internal leakage is inherent to the valves, which may increase over the life cycle.
Type H-4WEH…
The pilot oil supply is implemented externally - via channel X - from a separate pressure supply.
The pilot oil return is implemented externally - via channel Y - into the tank.
Type H-4WEH…E…
The pilot oil supply is implemented internally from channel P of the main valve.
The pilot oil return is implemented externally - via channel Y - into the tank. In the subplate, port X is closed.
Type H-4WEH…ET…
The pilot oil supply is implemented internally from channel P of the main valve.
The pilot oil return is implemented internally - via channel T - into the tank. In the subplate, ports X and Y are closed.
Type H-4WEH…T…
The pilot oil supply is implemented externally - via channel X - from a separate pressure supply.
The pilot oil return is implemented internally - via channel T - into the tank. In the subplate, port Y is closed.
Use of the throttle insert (5) is necessary if the pilot oil supply in channel P of the pilot control valve is to be limited (see below).
The throttle insert (5) is inserted in channel P of the pilot control valve.
