The Bosch Rexroth H-4WEH16E7X/6EG24SK4QM0G24 (R901181740) is a high-performance industrial hydraulic valve designed for reliable switching of oil flow direction in accordance with its spool symbol, Symbol E. This pilot-operated spool valve features external pilot oil supply and return, with a maximum pressure capability and a connector pole PE for electrical connections as per EN standards. It is solenoid-actuated, with the actuation powered by a 24 VDC supply voltage. The valve is engineered for subplate mounting and conforms to NFPA T3.5.1 R2 D03 and ISO 4401 size standards, ensuring compatibility with common industry practices. It offers multiple switching positions and is equipped with NBR seals suitable for various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, and HFC. Its design includes return springs that maintain the main control spool in the central position without pilot pressure. The valve's internal leakage characteristic is by design and may increase over its lifecycle. Additionally, it features pressure centering of the main control spool type HWEHH which allows for precise control by pressurization of the front faces of the spool. The pilot oil supply can be externally sourced via channel X from a separate pressure supply or internally from channel P of the main valve depending on the type (HWEHE or HWEH...ET...), while pilot oil return options include external via channel Y or internal via channel T into the tank. For applications requiring controlled pilot oil flow rates, throttle inserts can be utilized. The valve offers various actuation types including spring or pressure centering and end position choices like spring or hydraulic end positions. Additional optional features include manual override, switching time adjustment, preload valves in channel P of the main valve, stroke setting, and spool position monitoring to cater to specific application needs. This Bosch Rexroth hydraulic valve stands out for its versatility and adaptability to various operational requirements in sophisticated hydraulic systems.
