The RFP 50 model engineered by Doa, is a hydraulic valve, intended for the control of flow and pressure. This tool operates with the use of an output line, manipulated by two cartridges- one for the flow and one for the pressure.
This Doa hydraulic valve is provided in two configurations- one with a fixed flow regulation and the other with an adjustable flow regulation. The 1st type offers a stationary flow with preset settings at the factory. On the other hand, the 2nd type presents a flow that can be regulated by the operator.
