The Basics of Control Valves in a Hydraulic System

These advantages include high power-to-weight ratio, having the capability of being stalled, reversed, or operated intermittently, as well as having the capability for fast response and acceleration. Fluid power systems also offer reliable operation and a long service life.

In hydraulic systems​, the liquid used must be mostly incompressible, or very dense. For a variety of applications, utilizing a liquid to move machinery is more desirable than drier methods. Using a liquid will not cause the same type of wear on the system, and also will not require as many moving parts. Additionally, motion is more precise and the equipment will run much smoother than Hydraulic Pump For Cylinder would with more mechanic means.

Hydraulic control valves are used to control pressure in a hydraulic fluid power system. These valves control the pressure, flow rate and direction of the flow. Hydraulic valves can be defined in many different ways. Oftentimes, a given valve will be named differently when it is used in different applications. Hydraulic valves permit liquid to enter or leave specific spaces throughout the hydraulic system. Commonly, hydraulic valves are used with hydraulic pumps and cylinders to control the flow of the liquid.

Generally, hydraulic valves are classified based on their functions, including pressure, flow and directional control vales; or based on their control mechanisms, such as, on/off, servo, and proportional electrohydraulic valves. Hydraulic valves can also be classified based on their structures, such as spool, poppet, and needle valves. A hydraulic valve controls a fluid power system by opening and closing the flow-passing area of the valve.
