Proportional Directional Valve 4WRTE25E1-350L-4X/6EG24K31/F1M - Bosch Rexroth R900978068

Long cable runs between cabinet and valve argue against a voltage interface. This pilot-operated proportional directional valve in size 25 works with a 4 to 20 mA current command value and meters 350 l/min nominal flow at 350 bar.

Benefits

• 4 to 20 mA command value, insensitive to voltage drop on long lines and to electrical interference.
• 350 l/min nominal flow at 350 bar, flow up to 870 l/min through size 25.
• Spool symbol E1 with 3 switching positions across four ports.
• External pilot oil supply and external pilot oil return separate the pilot stage from the main circuit.
• On-board electronics with internal spool position feedback, no extra closed-loop amplifier required.
• 18 kg installed weight, NBR seals for HL fluid, connector 7-pole (6 + PE) to EN 175201-804.

Technical data

Applications

Suited to widely distributed hydraulic stations in rolling mills, paper machines and foundries. In test rigs where several valves are driven from one central cabinet the current command value stays stable. Mounting is on a subplate to ISO 4401-08-08-0-05.
