The 4WRDE16W1-200L-5X/6L24EK9/WG152V valve is part of the 4WRDE Directional Control Valves series from Bosch Rexroth and is used to direct and meter hydraulic flow in automated machinery. Its nominal size of 16 defines the mounting envelope and establishes a flow path large enough for the rated capacity. A maximum flow of 460 l/min lets the valve supply sizable cylinders or motors without excessive pressure loss, while a dither frequency of 400 Hz minimizes stick-slip during small position changes. Integrated electronics run on a nominal supply of 24 VDC and stay operative up to the 36 VDC limit to withstand voltage fluctuations. An IP65 protection class keeps dust and low-pressure water jets away from internal components, and the ISO 4401-07-07-0-05 porting pattern aligns the body with standard subplates. Each service port a, b, p, and t is drilled to 20 mm, giving low velocity head loss through the block.
A pilot oil flow of 15.6 l/min at 250 bar allows rapid spool actuation, and a control chamber volume of 2.9 cm³ governs the stroke from 0 to 100 percent command for predictable dynamics. Hydraulic oils up to 380 mm²/s viscosity can be processed, provided ambient temperature stays below 60 °C and fluid temperature does not exceed 80 °C, limits chosen to protect the FKM seals installed at all pressure interfaces. The valve incorporates a WG shut-off element so downstream lines can be isolated when the unit is de-energized. A mass of 10.5 kg enables single-person handling during cabinet or manifold installation.
