The 2076-166 work port relief valve serves as a pressure regulation component within the hydraulic control assembly of the lift arm system. By monitoring the fluid pressure within the circuit, it ensures that operational limits are maintained during machine use. When the hydraulic pressure reaches the calibrated threshold of 240 bar, the valve opens to divert excess flow, preventing potential damage to the hydraulic lines, actuators, and associated control components.
This component is specifically configured for use in the Terex PT100G model, including units with serial numbers DTM 00101 and later. It integrates directly into the lift arm control valve bank to manage pressure spikes that occur during heavy lifting or implement operation. Proper calibration of this valve is necessary to maintain the intended functionality and responsiveness of the lift arm.
Work port relief valves are used in hydraulic systems to provide localized pressure protection for specific circuits. By venting excess pressure back to the reservoir, these valves safeguard individual hydraulic functions from over-pressurization, which helps maintain the integrity of the overall hydraulic circuit and connected attachments.
