275 Pressure Relief Valves DEVICE SELECTION GUIDE 1.Device Size: Allbro offers TWO sizes of devices. The size required is dependant on the volume of oil that is required to be discharged. • T50 for volumes up to 3,000 liters. • T80 for volumes up to 9,000 liters. 2.

Pressure relief valves mount between the pump and valve system to protect against overloads. A suitable pilot valve may be used to "vent" the balanced piston relief valve when the system does not require power. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and reducing operating costs.

Re-seal pressure is defined as the downstream pressure at which the check valve closes bubble-tight. Example: For a valve with a spring having a rated cracking pressure of 25 psig (1.72 bar), the actual cracking pressure ranges between 20 and 30 psig (1.38 and 2.07 bar). The re-seal pressure range would be 16 to 20 psig (1.10 to 1.38 bar).
