A review of flow control methods

Flow control is a very common objective in fluid power systems. Usually, controlling the force, velocity, position, etc. of hydraulic actuator is achieved by adjusting the flow rate of the hydraulic fluid.

Description
Summary:Flow control is a very common objective in fluid power systems. Usually, controlling the force, velocity, position, etc. of hydraulic actuator is achieved by adjusting the flow rate of the hydraulic fluid. There are various techniques in which flow can be controlled. Choosing the appropriate flow control method depends on several factors including the systems requirements, the available space and budget. In this paper, a review of the fluid flow control techniques is presented. Those various ways of controlling fluid flow were discussed based on the available literature. The working principle of each flow control method was described. A discussion about those techniques in terms of efficiency, cost, complexity, and the need to accessories is given in this work. Advantages and disadvantages of each flow control strategy are presented. This paper can be used a guide when selecting the most appropriate flow control method when designing a fluid power system.
