The Bosch Rexroth H-4WEH 16 J7X/6EW110RNEXETZ2/B10D3V (R900773337) is a high-performance directional spool valve with electrohydraulic actuation designed to control the start, stop, and direction of fluid flow. This model features a main valve with housing, a main control spool, return springs, and a pilot control valve equipped with solenoids for precise operation. The main control spool is maintained in its initial position by the springs or through pressurization, allowing for consistent performance even in vertical valve positioning. This particular model has been engineered for use in potentially explosive atmospheres and is suitable for subplate mounting with porting patterns according to ISO standards. It offers various operational capabilities such as spring centering, spring end position, or hydraulic end position and includes wet-pin DC or AC solenoids. The solenoid coil can be rotated by 90 degrees to accommodate different installation requirements. For ease of manual operation, an optional auxiliary operating device can be included. The electrical connection is designed as an individual connection with a cable gland for secure and reliable power supply. Additionally, this valve offers optional features like switching time adjustment to cater to specific application needs and a preload valve in channel P of the main valve to enhance system stability. The Bosch Rexroth H-4WEH series valves are known for their inherent internal leakage due to their design principle; however, this is considered normal and may increase over the life cycle of the product. This particular model provides flexibility in pilot oil supply and return configurations – externally via channel X or internally from channel P of the main valve – ensuring compatibility with various hydraulic systems. Throttle inserts can be used if there's a need to limit pilot oil supply within the system. These features make this directional spool valve an adaptable solution for sophisticated hydraulic applications requiring robust performance and precise flow control.
