low pressure hydraulic relief valve

Model PR low pressure relief valves are used in systems to maintain a desired pressure level. Model PR is a proportional relief valves and not “pop” type 

The SPV/SPVF pressure relief valve is a directly controlled slide valve for installation in pipelines and is used to safeguard low-pressure hydraulic 

The LPR series is a range of low pressure relief valves. The valve is operated by an internal diaphragm that is much larger than the flow area.

PRESSURE RELIEF VALVE SELECTION AND APPLICATIONS FOR HYDRAULIC SYSTEMS Assoc. Prof. Dr. M. Sc. Ergur H. Sevil Abstract: The flow-pressure relationship is an important external characteristic of the pressure relief valve and the hydraulic circuit. So, many engineers have been put an effort on this topic for its significant impact on the overall hydraulic system.

The flow rate will help determine pressure.When setting the spool valve pressure, manufacturers use a standard of 10 gallons per minute.For higher flow rates, lower the pressure of the valve to make up for the higher pressure from the increased fluid flow. Conversely, low flow creates low pressure — to compensate, increase the pressure. .Pressure Relief Valve.

The relief valve just dumps its oil in the upper right area and it's pretty easy to tell if the relief is dumping pressure. My 886 had low hydraulic pressure and when I took the rear cover off above the PTO and pulled a remote lever I could see oil spraying around the hydraulic pump. When I took the pump out the O-ring was blown.
