The Bosch Rexroth H-4WEH 25 J6X/6EW110N9ETS2K4/V (R900931041) is a sophisticated electrohydraulic directional control valve designed for subplate mounting with a porting pattern conforming to ISO standards. This highly versatile valve can be configured as a 4/3 or 4/2 way version, equipped with features such as spring or pressure centering, spring end position, or hydraulic end position. It utilizes wet-pin DC or AC solenoids and offers options for an individual or central electrical connection. This model boasts several optional features that enhance its functionality, including manual override, switching time adjustment, a preload valve in channel P of the main valve, stroke setting, and spool position monitoring. The return springs in this model do not serve a return function but instead maintain the main control spool in the central position when depressurized and installed horizontally. The pilot oil supply for this valve can be configured in various ways: externally via channel X from a separate pressure supply (Type HWEH...T...) or internally from channel P of the main valve (Type HWEH...ET...). Similarly, pilot oil return can be external via channel Y into the tank (Type HWEHE) or internal via channel T into the tank (Type HWEH...ET...). For versions requiring controlled pilot oil supply flow rates, a throttle insert is necessary in port P of the pilot control valve. It's important to note that any modification of the pilot oil supply should only be carried out by authorized specialists or at the factory. Users must adhere to maximum admissible operating parameters for external pilot control valves and observe minimum and maximum pilot pressures as specified in technical data sheets to prevent high-pressure peaks. A B throttle insert may be required in port P of the pilot control valve to regulate pressure peaks appropriately.
