Directional Spool Valve 4WEH32U6X/6EG205N9K4 - Bosch Rexroth R900776953

The flow rate of a main axis decides the size of the directional valve. The 4WEH32U6X/6EG205N9K4 is pilot-operated and switches up to 1100 l/min to symbol U, with external pilot oil supply and external pilot oil return.

Benefits

• Maximum flow of 1100 l/min in size 32 with mounting pattern ISO 4401-10-09-0-05.
• Symbol U with 3 switching positions and 4 ports.
• External pilot oil supply and return allow the pilot pressure to be set independently of the main pressure.
• Solenoid voltage 205 VDC through a connector 3-pole (2 + PE) according to EN 175301-803.
• Operating pressure up to 280 bar at a mass of 35 kg.
• NBR seals for HL hydraulic fluid.

Technical data

Applications

The valve controls main cylinders in presses, rolling mills and large power units whose axes draw several hundred litres per minute at rapid speed. The 205 VDC solenoid voltage comes from a rectifier supply of the kind common in older plant concepts. NBR seals are fitted for mineral oil of class HL.
