Hydraulic valves

Hydraulic fluid pressure used to control the flow and direction of the components.Which control the pressure as pressure control valves, flow control valves, known as traffic control and flows through ,off as directional control valve.
By use of pressure control valve into valve and relief valve,sequence valve.

(1) relief valve: to control the hydraulic system to which it is set in a constant state of stress. The relief valve as safety valve for overload protection. When the system fails, the pressure increases to limit possible damage value, the valve opens and the overflow port to ensure the security of the system.

(2) valve: the branch circuit to control the main loop than is the stability of the oil pressure down. The pressure control valve according to its different functions, can be divided into constant pressure reducing valve (output pressure of constant value) ©p or worse valve (the pressure difference of input and output value) and fixed ratio valve (between input and output pressure to maintain a certain ratio).

(3), sequence valves: can an executive component (such as hydraulic cylinders, wear, motor, etc.) after the action, and then the implementation of components in order to make other moves. Pump the pressure first campaign to promote the hydraulic cylinder
