FAQs About Hydraulic Relief Valves

Hydraulic systems use pressurized fluid to power everything from car brakes and landing gear, to garbage trucks, motorboat steering, forklifts, elevators, cranes, heavy digging equipment, robotics, logging equipment, and many other types of machinery. There are components that contain the fluid, apply the pressure, and convert the energy into making your machinery move. The parts include valves, pumps, cylinders, hoses, oil reservoirs, safety devices and other components.

Q: What is an open center or closed center hydraulic system?

A. Performing hydraulic work requires flow and pressure. The ability to control them is made possible with open center and closed center systems. With an open center system, oil continuously flows through the directional control valve whether or not the oil is being used. In other words, the flow is continuous and the pressure is intermittent. In a closed center system, the valve communicates with the pump so that the flow stops when a work section is not being used. In other words, the flow is intermittent but the pressure is continuous.

Q: How is pressure controlled in a hydraulic system?

A. Pressure control valves are the most common method of controlling pressure. They play a vital role in regulating the pressure of the fluid passing through pipes or tubing to prevent leakage and bursting. They are found in virtually every hydraulic system and include counter-balance valves, unloading valves, sequence valves, and other valves that work in different ways to control pressure fluctuations.

Q: What is a relief valve?

A. Relief valves are the most common type of pressure-control valves. They are present in hydraulic equipment to protect the pump and the system from excess pressure. Without it, pressure could build up and cause irreparable damage to the equipment, leading to costly replacements and the potential for serious injury.

Q: What can cause a relief valve to fail?

A. Contaminants like dirt, rust, sludge, or lint, wrong valve selection, and misalignment of valves are the common causes of relief valve failure. Other problems include excessive noise, pressure variations, difficulty in valve adjustment. Excessive noise is created as a result of high oil viscosity and faulty poppet or seat arrangement.
