| S. N. | Pressure control valves | Applications |
|---|---|---|
| 1 | Pressure relief valves | Relief valve opens and bypasses fluid when pressure exceeds its setting.These areused mostly in all circuits. |
| 2 | Pressure-Reducing Valve | This type of valve (which is normally open) is used to maintain reduced pressures in specified locations of hydraulic systems |
| 3 | Unloading Valves | high-low pump circuits where two pumps move an actuator at ahigh speed and low pressure, punching press, |
| 4 | Counter balance valves | They are used to prevent a load from accelerating uncontrollably. This situation can occur in vertical cylinders in which the load is a weight. This can damage the load or even the cylinder itself when the load is stopped quickly at the end of the travel |
