FLOW CONTROL VALVES
The control of flow is broadly divided into major types that include:
The control of flow is a major feature of hydraulic systems and there are a variety of methods available for this, which can be used with both fixed and variable displacement pumps. This chapter is concerned with the basic aspects of flow control valves and their characteristics that are of importance in the design and selection of hydraulic circuits.
5.2 DIRECTIONAL CONTROL VALVE
Spool-type valves provide the major method of controlling the direction of flow and are used extensively for many circuit functions that are discussed in the chapter ...
