The 4WRZE16W6-150-7X/6EG24N9ETK31/F1V proportional directional valve belongs to the WRZ Proportional Directional Valves series produced by Bosch Rexroth for hydraulic automation. It receives position commands through a 4–20 mA current interface and is powered by 24 V DC. Size 16 dimensions suit medium-capacity manifolds, while the W6 spool profile establishes balanced metering edges. With a pressure drop of 10 bar the valve delivers 150 l/min, and the main stage withstands 350 bar operating pressure. Both the pilot oil supply and pilot oil drain are internal, removing external pilot lines. Mounting follows the ISO 4401-07-06-0-94 porting pattern to ensure interchangeability.
A 100 % duty cycle allows the unit to remain continuously energized without overheating. Electrical connection is through a DIN EN 175201-804 plug, and the enclosure meets IP65 to resist dust and water jets. A concealed manual override permits spool actuation during setup or service. The internal drain’s port T tolerates 30 bar back-pressure, and FKM seals provide chemical and temperature resistance. The valve weighs 13.6 kg when installed on a subplate.
