Product description
Type H-4WEH 16…XD...
The valve type H-4WEH is a directional spool valve with electro-hydraulic actuation. It controls the start, stop and direction of 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.
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). The pilot control valve is supplied with pilot oil via the control line (7). Supply can be effected 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.
When the solenoid is switched off, the pilot control spool returns into the initial position (except for impulse spool). The spring chamber (8) is unloaded to the tank.
The pilot oil from the spring chamber is displaced into channel Y via the pilot control valve.
The pilot oil supply and return can be effected internally or externally.
The manual override (9) allows the control spool (10) to be moved without solenoid energization.
Notice:
The main control spool (2) is held in a central position by the return springs (3.1) and (3.2) in spring chambers (6) and (8) without pilot pressure, even if the valve is positioned for example vertically.
Due to the design principle, internal leakage is inherent to the valves, which may increase over the life cycle.
Pilot oil supply
"H-WEH"
The pilot oil supply is effected externally via the X channel from a separate pressure supply.
The pilot oil return is effected externally via the Y channel into the tank.
"H-WEH…E…"
The pilot oil supply is effected internally from the P channel of the main valve.
The pilot oil return is effected externally via the Y channel into the tank. In the subplate, port X is closed.
"H-WEH…ET…"
The pilot oil supply is effected internally from the P channel of the main valve.
The pilot oil return is effected internally via the T channel into the tank. In the subplate, ports X and Y are closed.
"H-WEH…T…"
The pilot oil supply is effected externally via the X channel from a separate pressure supply.
The pilot oil return is effected internally via the T channel into the tank. In the subplate, port Y is closed.
Throttle insert
The use of the throttle insert is necessary if the pilot oil supply in the P channel of the pilot control valve is to be limited.

2) | For symbols C, F, G, H, P, T, V, Z, an internal pilot oil supply is only possible if the flow from P → T in the central position (for 3-spool position valve) or while crossing the central position (for 2-spool position valve) is so large that the pressure differential of P → T reaches a value of at least 7.5 bar. At a pressure differential below 7.5 bar, a check valve with a cracking pressure of 7.5 bar must be installed in the return line to the tank. Pilot oil return Y must be realized externally. |
3) | For symbols C, F, G, H, P, T, V, Z, S (Symbol S only for Size 16) – by meansof a preload valve (not Size 10) or a correspondinglyhigh flow. |
4) | The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter. |

Special application conditions for a safe application
- Connection lines must be passed in a strain-relieved way. The first mounting point must be within 150 mm of the cable and line entry.
- In order to avoid dangers caused by static charge, the base and/or subplate on which the valve is to be fitted must be electrically conductive and included in the equipotential bonding.
- The valve solenoid must not be installed close to charge generating processes.
- Contact of the connection cable with the casing surface is to be prevented.

Notices:
- Switching time = 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 = 40 °C ±5 °C.
With different hydraulic fluid temperatures, variations may occur.
- The switching times increase by approx. 30 ms if the pressure reducing valve "D3" is used.
- The switching times have been determined under ideal conditions and may differ in the system, depending on the application conditions.

Performance limits : Important information
Notice (applies to all sizes):
The specified performance limits apply to the use with two directions of flow (e. g. from P to A and simultaneous return flow from B to T at a ratio of 1:1). Due to the flow forces acting within the valves, the admissible performance limit may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked, with flow in the same or in different directions). In such cases of use, please consult us.
The performance limit was determined when the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.
