A10VSO18~A10VSO100 DR Controller - A10VSO28

The DR Controller is a hydraulic pressure compensator designed for Rexroth A10VSO series pumps (A10VSO18 to A10VSO100). It regulates the pump’s output flow according to system pressure, automatically reducing displacement when the set pressure is reached — ensuring consistent and safe hydraulic performance.

Features:

• Compatible with the entire A10VSO18~A10VSO100 pump range.

• Provides direct pressure control with adjustable setting.

• Maintains steady output pressure while minimizing energy loss.

• Built from precision-machined steel for high durability and stability.

• Includes mounting gasket for secure installation and leak prevention.

Applications:

Ideal for industrial machinery, mobile hydraulic systems, and construction equipment that require precise pressure regulation and overload protection.

Function:

The DR Controller limits the maximum pump pressure by adjusting the swash plate angle. When the system pressure reaches the pre-set limit, the controller decreases pump displacement to maintain stable pressure — providing efficient energy use, smooth operation, and longer pump life.
