The Hawe RD11 is a high-performance, manually adjustable throttling valve, also known as a restrictor valve, designed for precise flow rate control in hydraulic systems. It is engineered to regulate the speed of hydraulic consumers by limiting the flow in one or both directions, depending on the configuration. The RD11’s robust screw-in cartridge design allows for straightforward installation into control blocks, making it a versatile and reliable component for various industrial and mobile hydraulic applications where accurate speed adjustment of actuators is critical.
