Advantages and Disadvantages of Open Center Hydraulic Systems

Open center hydraulic systems work by creating flow when a pump turns. This flow flows back into the reservoir through the central passage in the directional control valve. When the spool strokes, the flow is focused toward the load. The pressure is created as the flow passes through the valve and the load is moved. When the pressure is greater than the load, hydraulic work is executed. However, an open center system has certain disadvantages.

The advantages of this hydraulic system outweigh the disadvantages. This type of system is less complicated to maintain, requires less precision and requires less moving parts. However, it does increase the risk of accident. The high pressure of the fluid can result in work accidents if the pipeline is not strong enough. The disadvantages of an open center system include a longer service life. If you’re wondering what to look for in a hydraulic system, here are some tips to help you decide which type of system is best for your needs.

The main difference between an open center system and a closed loop system is its flow. An open center hydraulic system gets most of its flow from the reservoir and sends most of it back. A closed center system, on the other hand, takes most of its flow directly from the actuator return flow. An open center hydraulic system has fewer advantages, but an open center hydraulic system is better for some applications. This type of system is not suitable for mobile equipment, such as cars and trucks.
