Relief valves consist of two sections: the cover section and
the body section. The cover section includes a pressure
adjustment screw, a heavy spring, a poppet, a seat, and a
vent connection. The body section includes a piston, a light
spring, a seat, and the port connections.
Service parts and installation dimensions are not contained
in this manual. The parts and installation drawings listed in
Table 2 is available from any Vickers application engineeringoffice.
Relief valves are devices used to limit maximum pressure in
hydraulic systems. When system pressure starts to exceed
the pressure setting of the relief valve, a controlled amount of
Figure 1 illustrates the basic valve operation. The valve pressure
setting is determined by the adjusting screw position
which varies the heavy spring compression. The balanced
piston is normally held against the seat by the light spring.
System pressure is present in chamber A and is connected
to chamber B through orifice C.
hydraulic fluid bypasses through the tank port and limits the
system pressure to the valve setting. A fine incremented
adjustment assures precise regulation over wide pressureranges.
A Vickers relief valve provides a fast response with very low
pressure override characteristics because of its two-stage
balance piston design. The balance piston relief valve is so
named because in normal operation it is in hydraulic
balance. Further details are discussed in Section III.
Variations within each basic model series are covered in the
