Blaine, TN -- (SBWIRE) -- 09/26/2013 -- Hydraulic Valves are the principal components in all systems and are used to control the pressure and flow of fluid, usually oil, through a hydraulic pipe. They are also used to generate hydraulic power.
Hydraulic Valves are not new; in fact, various forms have been around since 2000 BC when the Chinese invented the stopper valve that was used in a bamboo water delivery system to control the salt-water flow.
The ancient Egyptians used valves to stop the Nile from flooding and in the 18th century BC, the prototype for modern valves controlled the direction in which water flowed.
When the steam engine was invented along came a compensation hydraulic valve that had the ability to adjust the flow. In other words, when the steam pressure increased, the plug valves controlled the intake and the exhaust of a steam engine.
These days there are several types including Pressure Hydraulic Valves, Directional Valves, and Flow Control Valves.
Pressure Hydraulic Valves, also known as pressure control valves are used to control the water pressure that flows through various hydraulic systems. Their function is to maintain the water pressure below a set limit. Dalton Bearing and Hydraulic sells different varieties of pressure valves that include unloading valves, pressure regulator valves, counter-balance valves and sequence valves.
Pressure regulators are used to manage and control fluctuations in water pressure. Sequence valves are two way and force two parts of the hydraulic system to open in sequence. Counter-balance valves are pressure controlled and prevent a hydraulic system from accelerating out of control. Unloading valves are used when the pressure of a hydraulic system is at a critical point and pressure needs to be relieved.
Directional Control Valves from Dalton Hydraulic primarily direct or control the flow of water in the desired direction. These types of valves start or stop the fluid flow. Directional Control Valves can have up to five openings or as little as two in order to direct the flow of fluid. These types of valves can be actuated electrically, hydraulically, pneumatically, manually or mechanically. The most common directional hydraulic valves are operated by a solenoid with check valves and four way spool valves.
Flow Control Hydraulic Valves are the final element allowing fluid to pass by adjusting the passage flow as directed by a controller. These types of valves prevent water flow from the effects of gravity when a hydraulic system is not running. Flow Control Hydraulic Valves ensure that the water does not flow through the system while remaining on stand-by.
