 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:
(a) Blocking or stopping of flow
(b) Direction of flow
(c) Pressure of flow media
(d) Flow quantity
