Rexroth Proportional Valve DA30-1-5X/315-10Y, 400l/min Flow, 315bar Pressure

The DA30-1-5X/315-10Y represents Rexroth's advanced electro-hydraulic technology, combining precision control with robust performance in medium-flow hydraulic systems. This proportional directional valve features a pilot-operated design that delivers smooth, stepless flow regulation up to 10 L/min at pressures reaching 315 bar.

Key technical advantages include:

• Exceptional control accuracy (±1% of full scale)
• Rapid response times (≤30ms for 0-100% signal change)
• Cast iron construction for durability in demanding industrial environments
• Compact dimensions (NG5 size)
• Modular architecture with field-replaceable spools and cartridges

• Automated production lines
• Mobile equipment control systems
• Test bench instrumentation
• Heavy machinery operations

• Integrated electronics (24V DC operation)
• LVDT position feedback
• SAE porting pattern
• IP65 protection rating

This valve is particularly effective in systems where both directional control and flow regulation are required, offering significant advantages over conventional switching valves through reduced pressure spikes and improved energy efficiency. The design's contamination resistance (NAS 1638 Class 8) ensures reliable operation in typical industrial hydraulic systems.

• Different spool overlaps
• Alternative feedback systems
• Customized control algorithms

For optimal performance, Rexroth recommends pairing with their VT-VRPA1 amplifier and using ISO VG 46 hydraulic fluid within specified temperature ranges (-20°C to +80°C). The valve meets international standards including ISO 4401 and CETOP RP121H.
