Hydraulic overflow valves are one of the most common types of valves to be used in hydraulic systems.
In fact, all systems which utilise a fixed-volume pump require a relief valve as a means of protecting the system from excess pressure.
There are many various designs of relief valves in use, including both direct-acting and pilot-operated valves.
Both types have their own advantages and disadvantages and are ideal for use in different systems.
