The Bosch Rexroth 4WS2EM16-2X/150B12ET315K8EV (R900716550) is a high-performance industrial hydraulic valve designed for precise and reliable control of oil flow direction. This direct-actuated valve features a size 16 component series X, with a maximum operating pressure of 315 bar and a nominal flow rate. It is equipped with an external amplifier and operates on a supply voltage of 24 VDC. This model's capabilities include high accuracy control due to its internal piston position feedback system and its innovative nozzle/flapper plate design. The 4WS2EM16-2X/150B12ET315K8EV valve is engineered for subplate mounting with a porting pattern that conforms to ISO standards, specifically the DIN 24340 form A, ensuring compatibility with various hydraulic systems. The valve offers flexibility in the type of actuation, which is electrical with external electronics, and it comes with round connectors for electrical connection. The connection diagram follows NFPA T..R D Size CETOP D standards. It also boasts multiple switching positions and weighs in at an efficient mass. Designed to withstand diverse operating environments, the Bosch Rexroth valve uses FKM seals compatible with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its construction enables it to control position, force, pressure or velocity in demanding applications. The model's servo valves can function as either two-stage or way versions and are noted for their durability due to wear-free control spool return elements. They offer options for either external or integrated electronics (OBE), with both the valve and integrated control electronics being adjusted and tested for optimal performance. Maintenance is simplified by features such as an accessible filter for the first stage and the ability to change pilot oil supply from internal to external without disassembling the valve. In summary, the Bosch Rexroth 4WS2EM16-2X/150B12ET315K8EV offers robust performance in controlling hydraulic systems' position, force, pressure or velocity through its advanced design features tailored for industrial applications.
