OPERATION
Main Relief Valve
The main relief valve is located at the inlet of the control valve. The valve poppet
protrudes into the open center passage as illustrated in Figure 2.
The main relief valve is pilot operated. This means a spear shaped pilot plunger controls the pressure at which the valve opens and permits a gradual opening of the relief valve. Note that a small hole is drilled through the poppet. This permits the same pressure to be maintained on both sides of the poppet during normal operation and helps control the gradual opening of the relief valve when pressure reaches the specified setting.
When a cylinder reaches the end of its travel or is held for any reason with the control valve spool in a power position, the main relief valve opens to protect the hydraulic system from damage. When the relief valve is open, oil is diverted to the reservoir.
1. When pressure in the open center passage reaches the pressure setting of the relief valve, the pilot plunger is forced off its seat.
2. Oil flows through the plunger seat faster than it can be supplied, creating a pressure differential (lower pressure) between the poppet and plunger.
3. The pressure in the open center passage then unseats the poppet and oil is diverted through the seat sleeve to the reservoir.
4. The relief valve will remain open until the cylinder moves or the control valve spool is returned to neutral.
