The Bosch Rexroth 4WRZEM16E150-1X/6EG24K31/A1D3M (R901155719) is an advanced electrohydraulically actuated proportional directional valve designed for precise control over hydraulic flow direction and magnitude in complex systems. This valve is characterized by its pilot control valve with proportional solenoids and a main valve that includes a main control spool, spring, and a position indicator. The functionality of the 4WRZEM16E150-1X/6EG24K31/A1D3M allows for the spool to maintain a central position when solenoids are de-energized, while energizing the solenoids proportionally shifts the spool to regulate pilot oil pressure and thus control flow through progressive orifice-type cross-sections. This model is equipped with an inductive position switch that provides feedback on the main control spool's position through two switching outputs, ensuring accurate monitoring capabilities within a superior control system. Designed with safety in mind, this valve meets stringent requirements for safety-related components in control systems as per category 3, EN ISO 13849-1 standards. It features internal pilot oil supply via port P or external supply via port X, and similarly, pilot oil return can be internal via port T or external via port Y. An optional manual override is available but should be used cautiously due to potential uncontrolled machine movements. Ideal for applications demanding high safety standards such as hydraulic press controls, the Bosch Rexroth 4WRZEM16E150-1X/6EG24K31/A1D3M valve incorporates fundamental safety principles as specified in ISO 4414. For installation, it requires subplate mounting conforming to ISO porting patterns and may necessitate a preload valve if specific conditions are met. The integration of electronics OBE (On Board Electronics), switching position indicators, and compliance with category 3 controls makes this valve well-suited for sophisticated safety-related parts of machine controls requiring precise fluid dynamics management.
