Hydraulic Control Valves

Valves can be classified according to their functions to three main types

1-Pressure Control Valves

2-Flow Control Valves

3-Directional Control Valves

Pressure Control Valves

It can be used to limit the maximum pressure (a relief valve), to set a back pressure (acounterbalance valve)or to pass a signal when a certain pressure has been reached (sequencevalves)

Counterbalance Valves (also called load holding valves)

 It is basically a relief valve but used in a particular application to set up a back pressure in a circuit

It is used in load lowering applications such as lift trucks, winched and presses.

The usual load pressure setting is 1.3 times the load-induced pressure, i.e., Ps=1.3 Pl
