Pressure control hydraulic valves by TRIDENT HYDRAULICS LIMITED are divided into two categories.
* Pressure Relief Valve
* Pressure Reducing Valve.
These relief valves are the control valves that are said to have high flow accommodation when compared to the pressure reducing valves. This is because the relief valves are known to be capable of leading all the flow of the system towards the tank. On the other hand, relief valves are the ones that affect the measurements of the pressure that is being put into the hydraulic system. Pressure reducing valves are known to be used for influencing the pressure of the hydraulic system output to another subsystem.
