Workport relief valve for Terex PT100G

The workport relief valve, part number 2076-163, serves as a pressure regulation component within the hydraulic control assembly of the Terex PT100G compact track loader. Its primary function is to manage hydraulic pressure by opening when the system reaches its limit, thereby preventing damage to hoses, cylinders, and other sensitive hydraulic hardware. By redirecting excess fluid flow back to the tank or return line, the valve maintains the system within safe operational parameters.

This component is specifically calibrated for the Terex PT100G and operates at a set pressure of 275 bar. It is integrated into the lift arm control valve assembly to ensure that the boom and attached implements remain protected against pressure spikes during operation. Proper calibration of this valve is necessary to maintain the integrity of the machine's hydraulic circuits.

In hydraulic systems, workport relief valves are used to protect individual actuators from pressure surges that may occur due to external loads or rapid control movements. These valves allow the hydraulic system to bypass fluid when pressure exceeds the predetermined threshold, shielding the circuit from mechanical stress and potential failure.
