The Bosch Rexroth H-4WEH16D7X/6EW110RNXEETSZ2/B10D3V (R901254986) is a sophisticated directional spool valve with electrohydraulic actuation designed to manage the start, stop, and direction of fluid flow. This model is part of the HWEH XE series and is characterized by its main valve housing, control spool, return springs, and pilot control valve which can include one or two solenoids. The main control spool is maintained in a neutral position either by the return springs or through pressurization. This particular valve operates by moving the pilot control spool via solenoid activation, which pressurizes one spring chamber while leaving the other depressurized. This action causes the main control spool to shift and connect or disconnect specific ports within the main valve, thus controlling fluid flow. The unit features manual override capabilities for non-solenoid actuation and has internal leakage as an inherent design characteristic. The pilot oil supply for this model can be configured externally via channel X from a separate circuit or internally from channel P of the main valve depending on the type within the HWEH series. Similarly, pilot oil return can be managed internally or externally into the tank. Notably, it includes options such as throttle inserts for regulating pilot oil supply in channel P of the pilot control valve. This Bosch Rexroth directional valve is suitable for subplate mounting with porting patterns that adhere to ISO standards. It offers versatility with options like spring centering, hydraulic end position selection, wet-pin DC or AC solenoids that are rotatable by 90 degrees, and an optional auxiliary operating device. Additionally, this model allows for electrical connections via individual connection with cable gland and provides optional features like switching time adjustment and preload valves in channel P of the main valve. Designed for use in potentially explosive atmospheres, this directional spool valve ensures precise flow control in various hydraulic systems where reliability and performance are critical.
