Rexroth Pilot Proportional Directional Valve

Product Description

Product Description:

The Bosch Rexroth 4WRZ16W8-150-7X/6EG24N9EK4/D3M (R900244327) is a cutting-edge pilot-operated proportional directional valve engineered to deliver unmatched precision and reliability in hydraulic flow control. As part of the renowned WRZ series, this valve combines advanced engineering with robust construction, making it ideal for demanding industrial, mobile, and construction applications.
 
Innovative Design for Optimal Performance
Featuring a dual-stage architecture, the 4WRZ16W8 integrates a proportional solenoid-controlled pilot valve with a spring-centered main spool. When de-energized, the centering spring ensures the spool remains in a neutral position, enhancing safety during system downtime. By activating either solenoid, users can proportionally shift the main spool via pilot oil pressure, establishing flow paths (P-A/B-T or P-B/A-T) with progressive orifice characteristics. This design enables seamless control of flow direction and rate, minimizing pressure surges and optimizing system efficiency.

Technical Advantages

 

  • Robust Construction: Built for durability, it supports subplate mounting with ISO-standard porting patterns, ensuring compatibility with diverse hydraulic setups.
  • Flexible Pilot Oil Supply: Pilot oil can be sourced internally via port P or externally via port X, adapting to system requirements.
  • Manual Override: An optional manual actuation feature allows emergency operation without electrical power, though caution is advised to prevent unintended movements.
  • High Performance: Rated for maximum pressures up to 350 bar and flows up to 150 L/min, it balances power and precision.

 

 

Engineered for Durability & Efficiency
Constructed with premium materials, the 4WRZ16W8 withstands harsh environments and extended use. Its compatibility with mineral oils (HL/HLP) and flame-resistant fluids (HFC) broadens its utility across industries. While proportional spool designs inherently allow minor internal leakage over time, adhering to ISO 4406 cleanliness standards and regular maintenance ensures prolonged service life.
 
Why Bosch Rexroth Leads in Hydraulics
Backed by Bosch Rexroth’s 130+ years of innovation, this valve offers:
 
  • Low hysteresis (<6%) for precise positioning
  • Wide operating temperature range (-20°C to +70°C)
  • Compatibility with modular systems (external amplifiers required for OBE functionality)
 
Ideal Applications
 
  • Industrial machinery (presses, injection molding)
  • Construction equipment (excavators, loaders)
  • Mobile hydraulics (agricultural vehicles, cranes)
 
Maximize Your System’s Potential
The 4WRZ16W8-150-7X/6EG24N9EK4/D3M is more than a valve—it’s a solution for achieving peak performance in critical hydraulic systems. Whether optimizing cycle times or enhancing safety, this model sets the standard for reliability, accuracy, and adaptability.
