Rexroth DA30-1-5X/315-10Y Proportional Valve for Industrial Hydraulic Systems

The Rexroth Proportional Valve DA30-1-5X/315-10Y is a high-performance proportional directional valve manufactured by Bosch Rexroth. This valve is specifically designed to meet the precise control requirements for flow and direction in industrial hydraulic systems, and is widely used in various hydraulic systems that demand high precision, fast response times, and high reliability.

This valve belongs to the Rexroth DA series and is suitable for hydraulic systems with medium flow rates. It features single pilot control functionality. The valve has a bore size of 5mm, making it suitable for hydraulic systems with medium to small flow rates. The maximum operating pressure of the valve is 315 bar, capable of meeting the requirements of high-pressure hydraulic systems. The valve has a rated flow rate of 10 L/min, making it suitable for medium-flow hydraulic systems.

This proportional valve employs a pilot-operated control structure, where an electrical signal controls the movement of the pilot valve spool, which in turn drives the main valve spool to achieve continuous regulation of hydraulic fluid flow direction and flow rate. Its core advantage lies in its ability to perform proportional control, meaning it can precisely regulate the movement direction and speed of hydraulic actuators (such as hydraulic cylinders or motors) based on the magnitude of the input electrical signal.
