 Hydraulic
valves control and direct the oil from the time it leaves , the pump
until it starts on its return to the reservoir in a hydraulic circuit.
The relief valve is almost always the first one encountered by the
oil after it leaves the pump. From that point on throughout the circuit,
the type of valve employed depends upon the design of the circuit.
In a very simple circuit the second and only other valve used will
probably be the master control valve. In a complex circuit the oil
may flow through a sequence valve, master control valve, reducing
valve, flow control valve, check valve and several others before it
finally returns to the reservoir.
Hydraulic valves as used in industrial
applications are built in several pressure ranges. The majority of
present applications are in the range of 0 to 1500 lb per sq in.,
but the trend is toward higher pressures. Various types of valves
are used in hydraulic systems to control or regulate the flow medium.
Basically valves are expected to control:
- Blocking or stopping of flow
- Direction of flow
- Pressure of flow media
- Flow quantity
The various parameters that need to
be controlled in the case of oil energy are as follows:
- In a hydraulic machine the actuators
make to and fro motion. Hence the direction of oil feeding the
cylinder or motor needs to be reversed. This means that the direction
of oil flow is an essential aspect of hydraulic operation. This
is achieved by direction control valves.
- Oil energy does the work due to
pressure in the oil system. In a mechanical or hydraulic system
there may be a need to increase or decrease the oil pressure depending
on the specific requirement. Hence a group of valves called pressure
control valves have been designed.
- The speed of the actuators needs
to be altered as per operational requirement. For this purpose
hydraulic systems use flow control valves.
