Valve Information:

The excavator relief valve is used to control the pressure and flow of the hydraulic system to protect the hydraulic system and hydraulic components from damage caused by excessive pressure and flow. When the pressure of the hydraulic system reaches the set value, the overflow valve will open, and the excess hydraulic oil will flow back to the oil tank to maintain the stability of the hydraulic system. In addition, the relief valve can also be used to control the speed and force of the hydraulic cylinder. The relief valve can also be used to control the speed and force of the hydraulic cylinder during excavator operation. By adjusting the flow of the overflow valve, the hydraulic cylinder can be moved slowly or quickly to meet the needs of different working situations.

FAQ:

Q: Does a pressure relief valve reduce flow?
A:PRVs are effectively multi-functional - by lowering outlet pressure and flow rate, they also help reduce excessive water consumption and plumbing noise.

Q:What is the difference between hydraulic pressure reducing valve and relief valve?

A: Pressure-reducing valves are used when maintaining consistent levels of pressure throughout an entire system is necessary, while pressure-relief valves are used when it's essential that extreme overpressure conditions be prevented from occurring within the system.

Q:What is the pressure relief valve on a diesel engine?
A: This pressure relief valve is responsible for regulating the fuel pressure in the fuel rail. Common rail injections systems run anywhere between 23,000 to 29,000 PSI – if fuel pressure rises above this the Fuel Pressure Relief Valve will open to allow that overflow pressure to escape into the return system.
