The valve type WEH 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).
For unobjectionable functioning, the hydraulic system has to be bled properly.
For valves with 3 spool positions, the main control spool (2) in the main valve is held in zero position or initial position by means of two springs, for valves with 2 spool positions by pressurization and spring. 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 port 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.
Notice:
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.
Valve type WH is a directional spool valve with hydraulic actuation. It controls the start, stop and direction of a flow. The directional valve basically consists of the valve housing (1), the main control spool (2), one or two return springs (3.1) and (3.2) at valves with spring return or spring centering as well as the diversion plate (11).
The main control spool (2) is actuated directly by pressurization. The main control spool (2) is held in zero or initial position by springs or pressurization. Pilot oil supply and return are external (see Pilot oil supply).
4/3 directional valve with spring centering of the control spool
With this version, the main control spool (2) is held in zero position by two return springs (3.1) and (3.2). Via the diversion plate (11), the spring chamber (6) is connected to port Y, the spring chamber (8) to port X.
With pilot pressure loading of one of the two front sides of the main control spool (2), the spool is moved to the spool position. In the valve, the required ports are connected in this way. The spring on the opposite side returns the spool to the zero or initial position at pressure relief of the pressurized control spool area.
4/3 directional valve with pressure centering of the main control spool
The main control spool (2) in the main valve is kept in the zero position by pressurization of the two front faces. One centering bush (12) rests on the housing and fixes the control spool position. By pressure relief of one front face, the main control spool (2) is moved to the spool position.
The unloaded control spool face displaces the returning pilot oil into channel Y (external) via the pilot control valve.
Notice:
The springs (3.1) and (3.2) do not have a return function in this version. They hold the main control spool (2) in central position in the depressurized condition and with horizontal installation.

For a pressure differential below 109 psi, a check valve with a cracking pressure of 109 psi is to be provided in the return line to the tank. An external pilot oil supply Y is required. |
| 6) | Pilot oil supply X internal is only possible for a pressure at P of minimum 65 psi. For symbols with negative overlap F, G, H, P, T, V, (S only NG16), a certain flow from P to T in the central position is necessary for this purpose (see "characteristic curves"). For symbols C, HC, Z, HZ, a flow of >42.3 US gpm is required during passing over the central position for NG16, for NG22, 25 and 32 a flow of >47.6 US gpm. If the required flows are not reached, a preload valve has to be used. When using a preload valve, the pressure differential of the preload valve of the corresponding size (see "Project planning information") is to be added to the corresponding pressure differential in case of direction of flow P ("see characteristic curves"). |

Switching times = Contacting at the pilot control valve until start of opening of the control edge in the main valve and change in the control spool stroke by 95 %
The switching times are measured according to ISO 6403 with HLP46, ϑoil = 104 °F ±9 °F). With different oil temperatures, variations are possible.
The switching times were determined using DC solenoids. They decrease by approx. 20 ms if AC solenoids are used.
The shut-off of the solenoid creates voltage peaks, which can be reduced by the use of suitable diodes.
The switching times increase by approx. 30 ms if the pressure reducing valve "D3" is used.
The switching times were determined under ideal conditions and may differ in the system, depending on the application conditions.
