Valve Information:


Features of the excavator relief valve include:
High stability: When the pressure of the hydraulic system reaches the set value, the overflow valve will automatically open, and the excess hydraulic oil will flow back to the oil tank to maintain the stability of the hydraulic system.
Strong flexibility: By adjusting the flow of the overflow valve, the hydraulic cylinder can be moved slowly or quickly to meet the needs of different working conditions.
Good reliability: The excavator relief valve is made of high-quality materials, which has a long service life and high reliability.
Simple installation: The excavator relief valve is small in size and light in weight, and easy to install.

FAQ:

Q: Where is the pressure relief valve diesel?
A:Pressure relief valves are always located upstream of a diesel, electric or even jockey pump check valves. This prevents a relief valve from affecting the enter system if it fails open.

Q:What is the main engine relief valve?

A: The cylinder relief valve is designed to relieve pressures in excess of 10% to 20% above normal. A spring holds the valve closed and its lifting pressure is set by an appropriate thickness of packing piece . Only a small amount of lift is permitted and the escaping gases are directed to a safe outlet.

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.
