Neutral position blocking
In PVRES 155B4211 two extra flow regulators (potentiometers) are fitted, these can be set independently of each other. The potentiometers limit the signal voltage (Us) and hence influence the flow from the proportional valve to connection A and B without affecting the maximum stroke of the PVRES. In brief you have the complete stroke of the handle while the flow is limited. The flow can be limited to max 25% of max flow.
