How Are Hydraulic Equipment Manufactured

Essentially all valves have the same structure which consists of the valve body, valve spool and components of operated valve spool movements.

• Threaded port type
• Sub-plate mounting type
• Cartridge type

Sub-plate assembly type

This valve is an industrial valve, similar to the threaded type and the only difference can be seen in the assembly. These valves have oil ports that are visible on the flat surface of the valve. These oil ports are bolted to this flat surface on the manifold. Oil ports will be placed between the manifold holes and oil leaks can be prevented by using an O-ring at each oil port.

Type of cartridge

This type of construction differs from the above types in that they have different principles and concepts. Cartridge-type valves have better flow and response than other types. Cartridge valves are also expensive.

Why are valves used in hydraulic systems?

In a hydraulic system, valves perform certain functions as control valves capable of controlling the operation of actuators. These valves can also control the pressure by controlling the oil flow. Some valves have multiple functions and an important example of this would be hydraulic proportional valves.
