It is recommended to have a relief valve pressure setting at least 25% higher than the maximum system operating pressure. One must be sure that set pressure should not be higher than the design pressure of the hydraulic system [5]. 2.

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.

The relief valve allows venting on an over-pressurised system and ensures the safety of operational personnel in the vicinity as well as prolonging the life of the hydraulic power unit and peripheral machinery. Venting takes place along an auxiliary flow way away from the system. Acting as a path of least resistance, the relief valve opens when

05/11/ · If a seal in one of the cylinders tears up internally it can send debris into the hydraulic valve. This will clog the valve’s internal relief passage and cause the relief valve to not open. When the system relief valve does not relieve, the pump will go to full pressure and a hose connection – only rated for 4000 psi – will burst.
