The Bosch Rexroth H-4WEH22D7X/6EG24N9K4 (R900942760) is a high-performance industrial hydraulic valve designed for reliable switching of oil flow direction as indicated by its hydraulic symbol D. This spool valve is pilot-operated and features external pilot oil supply and return. It is equipped with solenoid actuation, providing precise control over the valve's operations. The model supports a maximum pressure rating and can be connected via subplate mounting following the NFPA T3.5.1 R2 D03 and ISO 4401 standards. The valve has a specified size and comes with an electrical connector featuring a Connector pole PE according to EN standard, ensuring secure electrical connections for effective operation. It operates at a supply voltage of 24 VDC, which powers the solenoid for actuation. The design includes multiple ports for fluid control and can accommodate a max flow rate as per its specifications. This model includes NBR seals compatible with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC types. Its construction takes into account the inherent internal leakage that may increase over its lifecycle due to its design principle. The H-4WEH22D7X/6EG24N9K4 valve features return springs that ensure the main control spool remains in the central position without pilot pressure, even when vertically positioned. The main control spool is pressure-centered and can be shifted by relieving pressure from one side while the opposing side directs pilot oil externally via the pilot control valve. This model allows for both internal or external pilot oil supply options depending on the specific configuration of the system it's integrated into. Additional features include manual override capability, switching time adjustment options, preload valves in channel P of the main valve, stroke setting adjustments, and spool position monitoring to cater to various application requirements. The Bosch Rexroth H-4WEH22D7X/6EG24N9K4 offers flexibility in hydraulic system design with its modular build and capability for customization through different actuation types such as electrohydraulic or manual operation suitable for subplate mounting applications.
