Lincoln, North Dakota | Open center hydraulic system used a fixed displacement pump like a gear pump and are protected by a relief valve. They have constant flow. Any valves used with open center have to have an open path back to return while in neutral. Closed center hydrualic systems use pumps that are variable displacement or on demand. In closed center hydraulic systems there is no open path back to return untill a valve is moved. When the hydraulic valves are in neutral and there is no demand for flow the hydraulic pump operates in a standby mode untill there is a request for oil flow.
